The use of PET/CT imaging with new radiotracers enables a non-invasive assessment of the presence of the target of treatment in the whole body and provides the possibility to combine functional information with anatomical details. Endosteal scalloping of the cortical bone can be seen in benign lesions like Fybrous dysplasia and low-grade chondrosarcoma. Sclerotic or blastic bone metastases can arise from a number of different primary malignancies including prostate carcinoma (most common), breast carcinoma (may be mixed), transitional cell carcinoma (TCC), carcinoid, medulloblastoma, neuroblastoma, mucinous adenocarcinoma of the gastrointestinal tract (e.g., colon carcinoma, gastric carcinoma), Gadolinium is usually minimal or absent (see right image). Here an illustration of the most common sclerotic bone tumors. However, a specific density range has not been specified for those terms 1. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. (2007) ISBN:0781765188. Fibro-osseous lesion like fibrous dysplasia. A sclerotic border especially indicates poor biological activity. Most primary bone tumors are seen in patients In patients > 30 years we must always include metastases and myeloma in the differential diagnosis. The differential diagnosis mostly depends on the age of the patient and the findings on the conventional radiographs. In the late stage of OA, the main feature is subchondral bone sclerosis, whose microarchitectural characteristics are elevated apparent density, increased bone volume, . On the right T2-WI with FS of same patient.. MRI features high sensitivity and high specificity for the demonstration of bone metastases in general and for assessing the bone marrow 2,3. 2021;13(22):5711. More heterogenous and irregular with bony trabecular destruction and possible extension beyond the confines of the cortex. Radiological atlas of bone tumours of the Netherlands Committee on Bone Tumors Central location most common with some expansion and cortical thinning. A brain MRI can . The contour of the involved bone is usually normal or with mild expansive remodelling. The zone of transition only applies to osteolytic lesions since sclerotic lesions usually have a narrow transition zone. Clin Orthop Relat Res. Guidelines for the Diagnostic Management of Incidental Solitary Bone Lesions on CT and MRI in Adults: Bone Reporting and Data System (Bone-RADS). Azar A, Garner H, Rhodes N, Yarlagadda B, Wessell D. CT Attenuation Values Do Not Reliably Distinguish Benign Sclerotic Lesions From Osteoblastic Metastases in Patients Undergoing Bone Biopsy. Generally, this just follows common sense some lesions should logically be expected to be focal, others multifocal, and yet others diffuse or systemic. Radiological hallmark: formation of a chondroid (cartilagenous) matrix, which presents as punctuated, stippled or popcorn-like calcifications. Bone scintigraphy (99mTc MDP) is very sensitive for the detection of osteoblastic providing information on osteoblastic activity but suffers from specificity with a false-positivity rate ranging up to 40% 1. Mass displaces and involves both the right 10 th intercostal artery, as well as more superior right 9 th intercostal artery. Click here for more information about bone island. Recommendation: No specific imaging recommendation. Arthritis Rheum., 42 (2012), pp. Here a chondrosarcoma of the left iliac bone. There are no calcifications. Osteoid osteoma (2) 7. Hall F & Gore S. Osteosclerotic Myeloma Variants. After an injury, different types of fluid can build up in a bone. Several genes have been discovered that, when disrupted, result in specific types . CT imaging example of the location pattern of sclerotic bone lesions in the skull, spine, and pelvis of TSC patients and control subjects. 1. Aggressive periosteal reaction Location within the skeleton FIGURE 2.7 Computed tomography of osteoid osteoma. To determine if sclerotic bone lesions evident at body computed tomography (CT) are of value as a diagnostic criterion of tuberous sclerosis complex (TSC) and in the differentiation of TSC with lymphangioleiomyomatosis (LAM) from sporadic LAM. A molecular classification has been also proposed. Gulati V, Chalian M, Yi J, Thakur U, Chhabra A. Sclerotic Bone Lesions Caused by Non-Infectious and Non-Neoplastic Diseases: A Review of the Imaging and Clinicopathologic Findings. A periosteal reaction with or without layering may be present. Click here for more examples of chondrosarcoma. If the osteonecrosis is located in the epiphysis, the term avascular osteonecrosis is used. Typical bone metastases are osteolytic (87.5%), with medullary origin (91.6%), and they cannot be distinguished from other osteolytic metastases on the basis of imaging criteria alone. Ulano A, Bredella M, Burke P et al. Bone islands can be large at presentation. The cause of sclerotic lesions was assessed histologically or by clinical and imaging follow-up. brae in keeping with diffuse bone infarcts. (A) Small radiolucent lesion exhibiting a thin sclerotic border (arrow) is present in the lateral cortex of the distal tibia of a 13-year-old boy. Distinction of Long Bone Stress Fractures from Pathologic Fractures on Cross-Sectional Imaging: How Successful Are We? growth of osteohondroma in skeletally mature patients, irregular or indistinct surface of lesions, soft tissue mass with scattered or irregular calcifications. In the case of benign, slowly growing lesions, the periosteum has time to lay down thick new bone and remodel it into a more normal-appearing cortex. The sagittal T1WI and Gd-enhanced T1W-image with fatsat show a large tumor mass infiltrating a large portion of the distal femur and extending through the cortex into the soft tissues. Unable to process the form. Bone and Joint Imaging. If you can find evidence of subchondral collapse or the typical lucent/sclerotic appearance of the necrotic bone in the weight-bearing bone, then osteonecrosis becomes a much more likely diagnosis. Differential diagnosis based on the periosteal reaction and the extensive edema: Here a patient with a juxtacortical sclerotic mass of the proximal humerus (left). Cancers (Basel). The image shows a calcified lesion in the proximal tibia without suspicious features. A Codman's triangle refers to an elevation of the periosteum away from the cortex, forming an angle where the elevated periosteum and bone come together. In this case we see the pathognomonic triad of bone expansion, cortical thickening and trabecular bone thickening in the mixed lytic and sclerotic phase of Paget's disease of right hemipelvis. MRI also may detect the nidus, combined with abundant bone marrow and soft tissue edema. Osteoblastic bone metastases are characterized by increased bone formation 2. If the disorder it is reacting to is rapidly progressive, there may only be time for retreat (defense). DD: Ganglion cyst, osteomyelitis, GCT, ABC, enchondroma. This is a routine medical imaging report. Case 7: metastases from prostate carcinoma, Sclerotic bone pseudolesions - external artifact, bizarre parosteal osteochondromatous proliferation (Nora lesion), conventional intramedullary chondrosarcoma, dysplasia epiphysealis hemimelica (Trevor disease), solitary bone plasmacytoma with minimal bone marrow involvement, mixed lytic and sclerotic bone metastases, Lodwick classification of lytic bone lesions, Modified Lodwick-Madewell classification of lytic bone lesions. However, a specific density range has not been specified for those terms 1. AJR 1995;164:573-580, Online teaching by the Musculoskeletal Radiology academic section of the University of Washington, by Theodore Miller March 2008 Radiology, 246, 662-674, by Nancy M. Major, Clyde A. Helms and William J. Richardson. Development in centrally located osteochondromas like the pelvis, hip and shoulder is most common. Skeletal Radiol. NOF, fibrous dysplasia, multifocal osteomyelitis, enchondromas, osteochondoma, leukemia and metastatic Ewing' s sarcoma. 3, Increased uptake on bone scan associated with a solitary sclerotic lesion is atypical and therefore more worrisome, but largely unhelpful as there are many reports of bone islands having increased Tc-99 m hydroxydiphosphonate (HDP) uptake. Osteomyelitis is a mimicker of various benign and malignant bone tumors and reactive processes that may be accompanied by reactive sclerosis. The mnemonic I VINDICATE is a commonly used mnemonic for the differential diagnostis of any radiological lesion. It is a feature of malignant bone tumors. A Novel Classification System for Spinal Instability in Neoplastic Disease: An Evidence-Based Approach and Expert Consensus from the Spine Oncology Study Group. 33.1d). Bone cements such as polymethyl methacrylate and calcium phosphates have been widely used for the reconstruction of bone. Age: most commonly seen in 10-25 years, but may occur in older patients. Here a patient with a broad-based osteochondroma with extension of the cortical bone into the stalk of the lesion. Here CT-images of a patient with prostate cancer. In the group of malignant small round cell tumors which include Ewing's sarcoma, bone lymphoma and small cell osteosarcoma, the cortex may appear almost normal radiographically, while there is permeative growth throughout the Haversian channels. W. B. Saunders company 1995, by Mark J. Kransdorf and Donald E. Sweet Disappearane of calcifications in a pre-existing enchondroma should raise the suspicion of malignant transformation. Uncommonly it can be difficult to differentiate a stress fracture from a pathologic fracture, that occurs at the site of a bone tumor. Rib lesions detected on bone scintigraphy often require further characterization with radiography or CT to improve specificity (Figs. Unable to process the form. Usually typical malignant features including permeative-motheaten pattern of destruction, irregular cortical destruction and aggressive (interrupted) periosteal reaction. Halo of increased signal on T2 W images about the low signal central lesion is suggestive of metastatic disease. The use of radiological imaging in medical care dates back to 1895 when The most common focal metastatic lesions originate from the breast (37%), lung (15%), kidney (6%), and thyroid (4%) 43. Biopsy revealed dedifferentiated chondrosarcoma. Check for errors and try again. Office Phone: (517) 205-6750. Notice that there are small areas of ill-defined osteolysis. Sclerotic Lesions of the Spine 1311. predominant hypointensity on all imaging sequences mimicking a sclerotic process due to a variety of fac- . Axial imaging for differentiation from Brodie abscess, osteoblastoma, stress fracture. Our patient had lytic bone lesions in (femur) long bones and also sclerotic lesions in the pelvic which was . This is opposed to myositis ossificans which may present very close to the cortical bone, but maturation develops from the center to the periphery. Bone cyst is one of the manifestations of CGL with AGPAT2 mutation. Ossifications or calcifications can be present in variable amounts. Infections, a common tumor mimicker, are seen in any age group. Osteoblastic metastases (2) 1. Usually stress fractures are easy to recognize. As current recommendations for tuberous sclerosis complex surveillance include renal MR performed i 2. Adamantinoma in case of a sclerotic lesion with several lucencies of the tibia in a young patient. 2. Lippincott Williams & Wilkins. Once we have decided whether a bone lesion is sclerotic or osteolytic and whether it has a well-defined or ill-defined margins, the next question should be: how old is the patient? Semin. W. B. Saunders company 1995, by Mark J. Kransdorf and Donald E. Sweet Generic Differential Diagnosis of Sclerotic Bone Lesions. Sclerosing bone dysplasias are skeletal abnormalities of varying severity with a wide range of radiologic, clinical, and genetic features. Radiologic Atlas of Bone Tumors The homogeneous enhancement in the upper part with edema and cortical thickening are not typical for a low-grade chondrosarcoma. Multiple enchondromas are seen in Morbus Ollier. Continue with the MR-images. Bone scintigraphy can be either negative or show limited uptake. Finally, we conclude with a case of an incidentally presenting sclerotic vertebral body lesion. This 'neocortex' can be smooth and uninterrupted, but may also be focally interrupted in more aggressive lesions like GCT. AJR 2000; 175:261-263. Conclusion. Unable to process the form. Here some typical examples of bone tumors in the spine. Osteosarcoma (2) Here, we showed that sBT values are higher in patients presenting 496 with bone loss . Detecting a benign periosteal reaction may be very helpful, since malignant lesions never cause a benign periosteal reaction. Lesions in the bone are usually identified on radiographic images - chiefly X-rays - but also on CT and MRI scans. There were other features that favored the diagnosis of a low-grade chondrosarcoma like a positive bone scan and endosteal scalloping of the cortical bone on an MRI (not shown). Strahlenther Onkol. Multiple enchondromas and hemangiomas are seen in Maffucci's syndrome. Other benign lesions, like solitary bone cyst, fibrous dysplasia, chondroblastoma and other benign bone tumors may become inert and may also become sclerotic. For those that are possibly cancerous, a biopsy is conducted to identify it. (see diagnostic imaging pearls). 3. Well, generally, it means that it is due to a fairly slow-growing process. Another approach to the differential diagnosis of sclerotic bone lesions is to use the mnemonic I VINDICATE, which means 'I clear myself from accusation'. 1988;17(2):101-5. Plain radiograph and coronal T1-weighted contrast-enhanced fat-suppressed MR image of a mixed lytic and sclerotic lesion of the distal femoral diaphysis. Paget disease is a chronic disorder of unknown origin with increased breakdown of bone and formation of disorganized new bone. A T1w/T2-weighted (T2w) hypointense nonexpansile lesion is seen involving the sacrum (asterisk). Metastases and multiple myelomaIn patients > 40 years metastases and multiple myeloma are the most common bone tumors.Metastases under the age of 40 are extremely rare, unless a patient is known to have a primary malignancy.Metastases could be included in the differential diagnosis if a younger patient is known to have a malignancy, such as neuroblastoma, rhabdomyosarcoma or retinoblastoma. It is assumed that several tumor-derived growth factors increase osteoblast activity while osteoclast activity is restricted 3,4. Journal of Bone Oncology. Spine (Phila Pa 1976). Presentation: pain, mass, pathologic fracture. Here an image of a patient with chronic osteomyelitis. in Ewing's sarcoma or lymphoma. The benign type is seen in benign lesions such as benign tumors and following trauma. Notice that CT depicts these lesions far better (red arrows). These lesions were possibly misinterpreted as new when applying WHO criteria. Here some typical examples of bone tumors in the foot: Fundamentals of Skeletal Radiology, second edition In the table the most common sclerotic bone tumors and tumor-like lesions in different age-groups are presented. Incidentally discovered, benign lesions also called enostoses, which are islands of cortical bone located in the cancellous bone. Skeletal Radiol. There are calcified strands within the soft tissues. Adam Greenspan, Gernot Jundt, Wolfgang Remagen. Here two other lesions in different patients that proved to be chondrosarcoma. Lumbar CT-HU has the highest pooled correlation (r 2 =0.6) with both spine DEXA and lowest skeletal t-score followed by lumbar CT-HU with hip DEXA (r 2 =0.5) and lumbar MRI with hip (r 2 =0.44) and spine (r 2 =0.41) DEXA. Sclerotic bone lesions caused by non-infectious and non-neoplastic diseases: a review of the imaging and clinicopathologic findings Sclerotic bone lesions caused by non-infectious and non-neoplastic diseases: a review of the imaging and clinicopathologic findings Authors These lesions usually regress spontaneously and may then become sclerotic. Age is the most important clinical clue in differentiating possible bone tumors.There are many ways of splitting age groups, as can be seen in the table, where the morphology of a bone lesion is combined with the age of the patient. Infections and eosinophilic granulomaInfections and eosinophilic granuloma are exceptional because they are benign lesions which can mimick a malignant bone tumor due to their aggressive biologic behavior.

Mineralization in osteoid tumors can be described as a trabecular ossification pattern in benign bone-forming lesions and as a cloud-like or ill-defined amorphous pattern in osteosarcomas. Patients usually have sclerotic bone lesions before and lytic bone lesions after puberty. For the unexpected bone lesions, the distinguishing anatomic features and a generalized imaging approach will be reviewed for four frequently encountered scenarios: chondroid lesions, sclerotic bone lesions, osteolytic lesions, and areas of focal marrow abnormality. Fundamentals of Skeletal Radiology, second edition Solitary sclerotic bone (osteosclerotic or osteoblastic) lesions are lesions of bone characterized by a higher density or attenuation on radiographs or computer tomography compared to the adjacent trabecular bone. Sclerotic means that the lesions are slow-growing changes to your bone that happen very gradually over time. There are two kinds of mineralization: Chondroid matrix It can identify small or large tumors, multiple sclerosis (MS), encephalitis (brain inflammation), or meningitis (inflammation of the meninges that lie between the brain and the skull). For example: Differential Diagnosis of Focal or Multifocal Sclerotic Bone Lesions. Ahuja S & Ernst H. Osteoblastic Bone Metastases in Medullary Thyroid Carcinoma. In skeletally mature patients, GCTs begin in the metaphysics and extend deep to the subchondral bone plate of the articular surface. Cortical destruction is a common finding, and not very useful in distinguishing between malignant and benign lesions. Occasionally slowly enlargement can be seen. Osteoblastic metastatic disease (see Table 33.1): More often multiple with increased uptake on bone scan. Both of these entities may have an aggressive growth pattern. Frequently encountered as a coincidental finding and can be found in any bone. Magnetic resonance imaging of subchondral bone marrow lesions in association with osteoarthritis. . It could be blood or fluids released from fibrosis (scarred tissue) or necrosis (tissue death). The differential diagnosis of bone lesions that result in bony sclerosis will be given. These tumors may be accompanied by a large soft tissue mass while there is almost no visible bone destruction. It classically presents with nocturnal pain in young patients, painful scoliosis, and marked relief from NSAIDs (nonsteroidal anti-inflammatory drugs). Solitary lucent lesions in bone with a distinct margin are generally called "geographic" lesions, whether or not they have a sclerotic rim. However, not all epidermal inclusion cysts involve bone, and some are confined to the subcutaneous tissues. Fibrous dysplasia, Enchondroma, NOF and SBC are common bone lesions.They will not present with a periosteal reaction unless there is a fracture.If no fracture is present, these bone tumors can be excluded. Here on a radiograph the typical calcifications in the chondroid matrix of an enchondroma. Increased uptake on bone scan has been reported in bone islands, especially giant ones, but warrants imaging follow-up. Diffuse skeletal infarcts can be a common cause of diffuse skeletal sclerosis. 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. O'Sullivan G, Carty F, Cronin C. Imaging of Bone Metastasis: An Update. This image is of a 20 year old patient with a sclerotic expansile lesion in the clavicle. Consider progression of osteohondroma to chondrosarcoma when cartilage cap measures > 10 mm. AJR Am J Roentgenol. Interventional Radiology). Sclerosis is present from either tumor new bone formation or reactive sclerosis. Scuba Certification; Private Scuba Lessons; Scuba Refresher for Certified Divers; Try Scuba Diving; Enriched Air Diver (Nitrox) Oncol Rev. In the active phase there is multilaminar periosteal reaction and bone and soft tissue edema. Check for errors and try again. 2 ed. Typically a NOF presents as an eccentric well-defined lytic lesion, usually found as a coincidental finding. A periosteal reaction is a non-specific reaction and will occur whenever the periosteum is irritated by a malignant tumor, benign tumor, infection or trauma. ADVERTISEMENT: Supporters see fewer/no ads. 7. Plain radiograph in another patient shows irreglar mineralized lesion with elevation of the periosteum and cortical involvement. some benign entities in this region may mimic malignancy if analyzed using classical bone-tumor criteria, and proper patient management requires being familiar with these presentations. The most common appearance is the mixed lytic-sclerotic. Imaging of skull vault tumors in adults: Author: Pons Escoda, Albert Naval Baudin, Pablo . Differential diagnosis and PD-L1 PET/CT (PD-L1 positivity is defined as having at least one lesion with radiotracer uptake over the . Moreover, questions such as the . Enchondromas aswell as low-grade chondrosarcomas are frequently encountered as coincidental findings in patients who have a MRI or bone scan for other reasons. Home. This feature differentiates it from a juxtacortical tumor. However, these lesions are often underreported, mainly because the subject is not well known to general radiologists who struggle with the imaging approach and disease entities. Notice the numerous ill-defined osteoblastic metastases. Check for errors and try again. Because of the large dimensions with soft tissue extension on plain radiograph and axial T2-weighted MR image, a high grade chondrosarcoma was suspected. colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. Growth has been demonstrated well after skeletal maturity. However, cancers that metastasize to bone are very common. Diagnostic brain imaging tests can assess bone fractures, structural problems, blood vessel abnormalities, and changes in brain metabolism. The mean and maximum attenuation were measured in Hounsfield units. Fibrous dysplasia and eosinophilic granuloma more commonly present as osteolytic lesions, but they can be sclerotic. Resonance Imaging Saeed M. Bafaraj . World J Radiol. The role of imaging in SN lymphomas is to identify the primary site of disease, site for biopsy and to map the lesion in its entirety in cases of patients undergoing radiotherapy [ 15, 21 ]. We provide care in several areas of orthopedics, such as: hand and wrist care, foot and ankle care, and joint replacement. Notice that in all three patients, the growth plates have not yet closed. by Mulder JD, et al. Here two patients with a bizar parosteal osteochondromatous proliferation (BPOP), also called Nora's lesion. In order to classify osteolytic lesions as well-defined or ill-defined, we need to look at the zone of transition between the lesion and the adjacent normal bone. Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them. This is an example of progression of an osteochondroma to a peripheral chondrosarcoma. The image on the right is of a different patient who has an old NOF that shows complete fill in. A popular mnemonic to help remember causes of focal sclerotic bony lesions is: Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. A lumbar puncture (LP) is a diagnostic procedure used to obtain a sample of cerebrospinal fluid (CSF) to look for signs of infection or inflammation. Bker S, Adams L, Bender Y et al. This part corresponds to a zone of high SI on T2-WI with FS on the right. A mean CT attenuation threshold of 885 HU and a maximum attenuation threshold of 1060 HU has been found supportive in the differentiation of untreated osteoblastic and bone island in one study 7, but the exclusive use of attenuation values for the assessment of sclerotic bone lesions has been discouraged 8. Growth of the osteochondroma takes place in the cap, corresponding with normal enchondral growth at the growth plates. The illustration on the left shows the preferred locations of the most common bone tumors. UW Radiology Sclerotic Lesions of Bone <-Lucent Lesions of Bone | Periosteal Reaction-> What does it mean that a lesion is sclerotic? Bone islands demonstrate uniformly low The sclerotic lesion in the humeral head could very well be a benign enchondroma based on the imaging findings. The lesion is predominantly calcified. There are two patterns of periosteal reaction: a benign and an aggressive type. It can also be proven histologically. Fundamentals of diagnostic radiology. Sclerotic bone lesions are rare; commonly affects the axial skeleton (pelvis, spine, skull, ribs) and the patients are often symptomatic as opposed to the patients with lytic lesions who rarely have any symptoms. Diffuse bony sclerosis (mnemonic). Click here for more examples of eosinophilic granuloma. Less common: Fibrous dysplasia, Brown tumors of hyperparathyroidism, bone infarcts. The homogeneous pattern is relatively uncommon compared to the heterogeneous pattern. A periosteal chondroma may have the same imaging characteristics, however, these are almost always much smaller. Common: Metastases, multiple myeloma, multiple enchondromas. Henry Ford Hospital, Neuro Surgery, MI, 1999 Universitat Dusseldorf, Neuro Surgery, 1990 Universitaire Instelling Antwerpen, Neuro Surgery, 1983 by Mulder JD et al Causes: corticosteroid use, sickle cell disease, trauma, Gaucher's disease, renal transplantation. 12. Chrondroid tumors are more frequently encountered than bone infarcts. Subungual exostoses are bony projections which arise from the dorsal surface of the distal phalanx, most commonly of the hallux. The contour of the subchondral bone plate was maintained until day 3, but it was absorbed just under the cartilage defect from day 7 to 14. Sometimes a more solid periosteal reaction is present combined with cortical thickening and broadening of the bone. In some locations, such as in the humerus or around the knee, almost all bone tumors may be found. The evaluation of a solitary bony lesion in the spine may be more challenging and will often require additional diagnostic testing if benign imaging features are not present on MRI. CT-HU has stronger correlations with DEXA than MRI measurements. Well, generally, it means that it is due to a fairly slow-growing process. Sclerotic metastases arise from . 2021;216(4):1022-30.
