The MR image shows that the lesion has lobulated contours and nodular enhancement. 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. Here CT-images of a patient with prostate cancer. There are a number of other helpful findings you can look for that can help you to cone in on or away from specific entities in one of these differential lists. giant cell tumor, metastasis, and myeloma; (3) sclerotic . Yes, it is possible to have a clear lumbar puncture and still have Multiple Sclerosis (MS). Sclerosis can also be reactive, e.g. Contact Information and Hours. About Us; Staff; Camps; Scuba. Check for errors and try again. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. The most reliable indicator in determining whether these lesions are benign or malignant is the zone of transition between the lesion and the adjacent normal bone (1). Differential Diagnosis in Orthopaedic Oncology. Ali Mohammed Hammamy R, Farooqui K, Ghadban W. Sclerotic Bone Metastasis in Pulmonary Adenocarcinoma. 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. Finally, we conclude with a case of an incidentally presenting sclerotic vertebral body lesion. Common: Metastases, multiple myeloma, multiple enchondromas. Based on the morphology and the age of the patients, these lesions are benign. It could be blood or fluids released from fibrosis (scarred tissue) or necrosis (tissue death). A chondrosarcoma was diagnosed at biopsy. Notice the numerous predominantly osteoblastic metastases. Ossifications or calcifications can be present in variable amounts. However, a specific density range has not been specified for those terms 1. The images show on the left a typical osteolytic NOF with a sharp sclerotic border. The radiographic appearance and location are typical. sclerosing osteomyelitis of Garr, aggressive features might require an oncological referral and/or biopsy 1, history of malignancy will almost always require additional imaging, follow-up or oncologic referral, high CT attenuation values might help in the differentiation of bone island from osteoblastic metastases 5 but attenuation values should not be used exclusively for the assessment of sclerotic bone lesions 6, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. In the article Bone Tumors - Differential diagnosis we discussed a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. Many sclerotic lesions in patients > 20 years are healed, previously osteolytic lesions which have ossified, such as: NOF, EG, SBC, ABC and chondroblastoma. Click here for more examples of enchondromas. CT of Sclerotic Bone Lesions: Imaging Features Differentiating Tuberous Sclerosis Complex with Lymphangioleiomyomatosis from Sporadic Lymphangioleiomymatosis1. Sclerosis is usually the most prominent finding in subacute and chronic osteomyelitis. CT imaging example of the location pattern of sclerotic bone lesions in the skull, spine, and pelvis of TSC patients and control subjects. Here an incidental finding of several eccentric sclerotic lesions of the distal femur. J Korean Soc Radiol. In aggressive periostitis the periosteum does not have time to consolidate. Conclusion. Fibro-osseous lesion like fibrous dysplasia. The major part of the lesion consists of reactive sclerosis. colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. Mass displaces and involves both the right 10 th intercostal artery, as well as more superior right 9 th intercostal artery. Consider peripheral chondrosaroma in growing osteochondromas with or without pain after closure of the physeal plate. Confavreux C, Follet H, Mitton D, Pialat J, Clzardin P. Fracture Risk Evaluation of Bone Metastases: A Burning Issue. Distinguishing Untreated Osteoblastic Metastases From Enostoses Using CT Attenuation Measurements. 1, The classic bone island has a spiculated or paintbrush border and is much denser on CT than a osteoblastic metastasis. The differential for multifocal lesions happens to be identical to that for focal lesions. Solitary lucent lesions in bone with a distinct margin are generally called "geographic" lesions, whether or not they have a sclerotic rim. Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. Here an example of a patient with a stress fracture of the distal fibula. This 'neocortex' can be smooth and uninterrupted, but may also be focally interrupted in more aggressive lesions like GCT. Etiology Skeletal Radiol. Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them. A brain MRI can . MRI shows large tumor within the bone and permeative growth through the Haversian channels accompanied by a large soft tissue mass, which is barely visible on the X-ray. Here a lesion located in the epi- and metaphysis of the proximal humerus. Parkinson's disease, multiple sclerosis, brain tumors and brain trauma [2]. Usually one bone is involved. Diffuse bony sclerosis (mnemonic). Rib metastases may be osteolytic, sclerotic, or mixed. 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. (see diagnostic imaging pearls). AJR 2005; 185:915-924. The juxtacortical mass has a high SI and lobulated contours. Endosteal scalloping of the cortical bone can be seen in benign lesions like Fybrous dysplasia and low-grade chondrosarcoma. Starting on day 28, sclerotic changes surrounding the bone absorption area were detected. Arthritis Rheum., 42 (2012), pp. There is no calcification and lesions may be expansile. D'Oronzo S, Coleman R, Brown J, Silvestris F. Metastatic Bone Disease: Pathogenesis and Therapeutic Options. DD: Ganglion cyst, osteomyelitis, GCT, ABC, enchondroma. We provide care in several areas of orthopedics, such as: hand and wrist care, foot and ankle care, and joint replacement. Frequently encountered as a coincidental finding and can be found in any bone. The zone of transition only applies to osteolytic lesions since sclerotic lesions usually have a narrow transition zone. Metastatic sclerotic bone lesions present in three typical patterns, focal, variegated, or diffuse based on the histological origin of the primary tumor. Differentiation of Predominantly Osteoblastic and Osteolytic Spine Metastases by Using Susceptibility-Weighted MRI. These tumors may be accompanied by a large soft tissue mass while there is almost no visible bone destruction. In some cases however the osteolytic nidus can be visible on the radiograph (figure). Aggressive periosteal reaction (2005) ISBN: 9780721602707 -. 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. Urgency: Routine. 14. Ulano A, Bredella M, Burke P et al. The chondroid matrix is of a variable amount from almost absent to dens compact chondroid matrix. Amsterdam: Elsevier, 1993. Wide zone of transition Finally other clues need to be considered, such as a lesion's localization within the skeleton and within the bone, any periosteal reaction, cortical destruction, matrix calcifications, etc. If the osteonecrosis is located in the epiphysis, the term avascular osteonecrosis is used. (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. 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. Prevalence of 3-5% in patients with hereditary multiple osteohondromas. Less common: Fibrous dysplasia, Brown tumors of hyperparathyroidism, bone infarcts. Multiple enchondromas and hemangiomas are seen in Maffucci's syndrome. The location of a bone lesion within the skeleton can be a clue in the differential diagnosis. Osteosarcoma, chondrosarcoma, and Ewing's sarcoma are the most common types of bone cancer. 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. <-Lucent Lesions of Bone | Periosteal Reaction->. diffuse sclerotic metastases to the pelvis, sacrum and femurs. Typical presentation: well-defined osteolytic lesion in tarsal bone, patella or epiphysis of a long bone in a 20-year old with pain and swelling in a joint. 4 , 5 , 6. Kimura T. Multidisciplinary Approach for Bone Metastasis: A Review. A Novel Classification System for Spinal Instability in Neoplastic Disease: An Evidence-Based Approach and Expert Consensus from the Spine Oncology Study Group. Sclerotic bone metastases can arise from several different primary malignancies including 1-3: mucinous adenocarcinoma of the gastrointestinal tract (e.g. 2. It is most commonly located in the outer table of the neurocranium or in a paranasal sinus. There are two patterns of periosteal reaction: a benign and an aggressive type. 1. Uncommonly it can be difficult to differentiate a stress fracture from a bone tumor like an osteoid osteoma or from a pathologic fracture, that occurs at the site of a bone tumor. Hallmark of osteosarcoma is the production of bony matrix, which is reflected by the sclerosis seen on the radiograph. The sclerotic lesion in the humeral head could very well be a benign enchondroma based on the imaging findings. Subchondral bone attrition is the flattening or depression of the bone surface that forms part of a joint. Differentiating a bone infarct from an enchondroma or low-grade chondrosarcoma on plain films can be difficult or even impossible. A juxtacortical chondrosarcoma has be considered in the differential diagnosis when a mineralized lesion adjacent to the cortical bone is seen. Infection with a multilayered periosteal reaction. The cause of sclerotic lesions was assessed histologically or by clinical and imaging follow-up. . A high grade chondrosarcoma must be considered in the differential diagnosis. Increased uptake on bone scan has been reported in bone islands, especially giant ones, but warrants imaging follow-up. Sclerotic osteoblastic metastases must be included in the differential diagnosis of any sclerotic bone lesion in a patient > 40 years. Bone islands can be large at presentation. DD: old SBC. Metastases are the most common malignant bone tumors. Surrounded by a prominent zone of reactive sclerosis due to a periosteal and endosteal reaction, which may obscure the central nidus. Scuba Certification; Private Scuba Lessons; Scuba Refresher for Certified Divers; Try Scuba Diving; Enriched Air Diver (Nitrox) Enhancement after i.v. 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. A T1w/T2-weighted (T2w) hypointense nonexpansile lesion is seen involving the sacrum (asterisk). ( A1,A2) Transversal CT of the skull of a TSC patient and . A bone island larger than 1 cm is referred to as a giant bone island (12). This is an example of progression of an osteochondroma to a peripheral chondrosarcoma. As current recommendations for tuberous sclerosis complex surveillance include renal MR performed i by Mulder JD et al Materials and Methods Henry Ford Hospital, Neuro Surgery, MI, 1999 Universitat Dusseldorf, Neuro Surgery, 1990 Universitaire Instelling Antwerpen, Neuro Surgery, 1983 Here some typical examples of bone tumors in the foot: Fundamentals of Skeletal Radiology, second edition All images were evaluated for joint form, erosion, sclerosis, fat metaplasia and bone marrow oedema (BMO) by two independent readers. Mixed lytic/sclerotic lesion of right posterolateral 10 th rib, with extensive aggressive-appearing periostitis, as well as a multilobulated soft tissue component. Bone islands demonstrate uniformly low When you are considering osteonecrosis in your differential diagnosis, look at the joints carefully. Notice the homogeneous thickening of the cortical bone. SusanaBoronat, IgnasiBarber, VivekPargaonkar, JoshuaChang, Elizabeth A.Thiele . 4. Here Melorrheostosis of the ulna with the appearance of candle wax. The illustration on the left shows the preferred locations of the most common bone tumors. It is true that the usual appearance of skeletal metastases is that of focal lesions diffuse sclerosis occurs in only a small fraction of cases of skeletal metastases. Eosinophilic granuloma like osteomyelitis, can be a serious mimicker of malignancy (particularly Ewing sarcoma). 2021;216(4):1022-30. 6. Radiological hallmark: formation of a chondroid (cartilagenous) matrix, which presents as punctuated, stippled or popcorn-like calcifications. 5 Biopsy should be considered in atypical cases or in high-risk patients with primary malignancies associated with osteoblastic metastatic disease. Impact of Sclerotic. Click here for more examples of eosinophilic granuloma. Differentiating between a diaphyseal and a metaphyseal location is not always possible. 33.1a) and sagittal short tau inversion recovery (STIR; Fig. 3. Complete destruction may be seen in high-grade malignant lesions, but also in locally aggressive benign lesions like EG and osteomyelitis. Secondary bone cancer is much more common than primary bone . One can then apply various features of the lesions to this differential, and exclude some things, elevate some things, and downgrade others in the differential. Macedo F, Ladeira K, Pinho F et al. Lets apply the good old universal differential diagnosis to sclerotic bone lesions. Diffuse skeletal infarcts can be a common cause of diffuse skeletal sclerosis. Fundamentals of diagnostic radiology. Occasionally slowly enlargement can be seen. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Metastases must be included in the differential diagnosis of any bone lesion, whether well-defined or ill-defined osteolytic or sclerotic in age > 40. 2 ed. The cortical bone and bone marrow compartment are not involved. In patients > 30 years, and particularly > 40 years, despite benign radiographic features, a metastasis or plasmacytoma also have to be considered CT can detect osteoblastic metastases with a higher sensitivity than plain radiographs and shines in the assessment of bones which are characterized by a small bone marrow cavity and a high amount of cortical bone such as the ribs 2,3. Less dense on CT and more heterogeneous than bone islands. 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. Here a radiograph of the pelvis with a barely visible osteoblastic metastasis in the left iliac bone (blue arrow). Unable to process the form. MRI features high sensitivity and high specificity for the demonstration of bone metastases in general and for assessing the bone marrow 2,3. Many important signaling . The NK cell type is seen as a sheet of soft tissue in the nasal cavity with bone destruction and erosion without any sclerosis. AJR Am J Roentgenol. Osteoblastic metastases have a lower fracture risk than lytic or mixed bone metastases 11-13. post-treatment appearance of any lytic bone metastasis. . 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. Calcifications in chondroid tumors have many descriptions: rings-and-arcs, popcorn, focal stippled or flocculent. Polyostotic lesions > 30 years Diffuse bony sclerosis (mnemonic) Last revised by Joshua Yap on 28 Jun 2022 Edit article Citation, DOI & article data A mnemonic for remembering the causes of diffuse bony sclerosis is: 3 M's PROOF Mnemonic 3 M's PROOF M: malignancy metastases ( osteoblastic metastases) lymphoma leukemia M: myelofibrosis M: mastocytosis S: sickle cell disease Chrondroid tumors are more frequently encountered than bone infarcts. Here a well-defined mixed sclerotic-lytic lesion of the left iliac bone. This is a routine medical imaging report. Notice that the mineralization is predominantly in the periphery of the mass and that there is a lucent zone between the mass and the cortical bone. Signed by [redacted] on 1/17/2020 11:42 AM Narrative Notice that CT depicts these lesions far better (red arrows). In the cases in which the solitary sclerotic lesion has increased, uptake on bone scan, follow-up CT, or plain film imaging is recommended at 3-, 6-, and 12-month intervals. Notice that the cortical bone extends into the lesion. In breast cancer, metastases may present as lytic lesions that may become sclerotic expressing a favourable response to chemotherapy. In patients SWI:low signal intensity on the inverted magnitude and phase images 9. 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? If the patient had fever and a proper clinical setting, osteomyelitis would be in the differential diagnosis. Detecting a benign periosteal reaction may be very helpful, since malignant lesions never cause a benign periosteal reaction. Rapid growth of the mineralized mass is not uncommon. 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. This is extremely common in Pagets disease but extremely uncommon with a blastic metastasis. 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), 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. It is assumed that several tumor-derived growth factors increase osteoblast activity while osteoclast activity is restricted 3,4. . Here an illustration of the most common sclerotic bone tumors. Resonance Imaging Saeed M. Bafaraj . 33.1d). None of the patients had undergone prior treatment for the metastases. AJR Am J Roentgenol. The signal intensity on MR depends on the amount of calcifications and ossifications and fibrous tissue (low SI) and cystic components (high SI on T2). 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 ].
