Check for errors and try again. The chondroid matrix is of a variable amount from almost absent to dens compact chondroid matrix. 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. General Considerations The epiphysis, metaphysis and diaphysis may be involved. Here a lesion in the epiphysis, which was the result of post-traumatic osteonecrosis. Notice that there are small areas of ill-defined osteolysis. A T1w/T2-weighted (T2w) hypointense nonexpansile lesion is seen involving the sacrum (asterisk). Here some typical examples of bone tumors in the spine. An ill-defined border with a broad zone of transition is a sign of aggressive growth (1). Bone Metastases: An Overview. AJR 2000; 175:261-263. 9. Adam Greenspan, Gernot Jundt, Wolfgang Remagen. As current recommendations for tuberous sclerosis complex surveillance include renal MR performed i Park S, Lee I, Cho K et al. This is especially true when the injury involves the spine, hip, knees, or ankle. Case Report Med. Radiological hallmark: formation of a chondroid (cartilagenous) matrix, which presents as punctuated, stippled or popcorn-like calcifications. 2010;35(22):E1221-9. 1. Mild mass effect on adjacent lung, diaphragm, and liver. The differential for multifocal lesions happens to be identical to that for focal lesions. Several genes have been discovered that, when disrupted, result in specific types . In this paper, we review the recent years of literature on deep learning-based multiple-lesion recognition. A Novel Classification System for Spinal Instability in Neoplastic Disease: An Evidence-Based Approach and Expert Consensus from the Spine Oncology Study Group. Bone islands demonstrate uniformly low One study, using a mean attenuation of 885 HU and a maximum attenuation of 1,060 HU as cut-off values, distinguished the higher density bone islands from lower density osteoblastic metastases with 95% sensitivity and 96% specificity. Moreover, questions such as the . Non-ossifying fibroma which has been filled 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. Imaging of skull vault tumors in adults: Author: Pons Escoda, Albert Naval Baudin, Pablo . Amorphous mineralisation is present in most lesions. Here a patient with a broad-based osteochondroma. Here an illustration of the most common sclerotic bone tumors. 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. 2021;216(4):1022-30. 1. DD: old SBC. Click here for more detailed information about fibrous dysplasia. Consider peripheral chondrosaroma in growing osteochondromas with or without pain after closure of the physeal plate. Radiographic features that should raise the suspicion of malignant transformation on plain radiographs or CT include: Here the reactive sclerosis is the most obvious finding on the X-ray. On the right T2-WI with FS of same patient.. 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. Notice how easily MRI depicts these lesions. There are two tumor-like lesions which may mimic a malignancy and have to be included in the differential diagnosis. Sclerotic bone metastases typically present as radiodense bone lesions that are round/nodular with relatively well-defined margins 3 . The benign type is seen in benign lesions such as benign tumors and following trauma. When you are considering osteonecrosis in your differential diagnosis, look at the joints carefully. A brain MRI can . Notice the homogeneous thickening of the cortical bone. Osteoblastic metastases have a lower fracture risk than lytic or mixed bone metastases 11-13. post-treatment appearance of any lytic bone metastasis. On the left three bone lesions with a narrow zone of transition. A surface osteosarcoma could be considered in the differential diagnosis. Central location most common with some expansion and cortical thinning. The NK cell type is seen as a sheet of soft tissue in the nasal cavity with bone destruction and erosion without any sclerosis. Sometimes a more solid periosteal reaction is present combined with cortical thickening and broadening of the bone. Metastases must be included in the differential diagnosis of any bone lesion, whether well-defined or ill-defined osteolytic or sclerotic in age > 40. This benign reactive process is most commonly found adjacent to the cortex of phalanges of hands or feet (75%). 4 , 5 , 6. It may be spiculated and interrupted - sometimes there is a Codman's triangle. Plain radiograph and coronal T1-weighted contrast-enhanced fat-suppressed MR image of a mixed lytic and sclerotic lesion of the distal femoral diaphysis. Osteosarcoma, chondrosarcoma, and Ewing's sarcoma are the most common types of bone cancer. The sclerotic lesion in the humeral head could very well be a benign enchondroma based on the imaging findings. 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. 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. UW Radiology Sclerotic Lesions of Bone <-Lucent Lesions of Bone | Periosteal Reaction-> What does it mean that a lesion is sclerotic? In patients In patients > 30 years, and particularly > 40 years, despite benign radiographic features, a metastasis or plasmacytoma also have to be considered On the left three bone lesions with a narrow zone of transition. If the patient had fever and a proper clinical setting, osteomyelitis would be in the differential diagnosis. Check for errors and try again. Incidentally discovered, benign lesions also called enostoses, which are islands of cortical bone located in the cancellous bone. 14. Interventional Radiology). Fibro-osseous lesion like fibrous dysplasia. Unable to process the form. Scuba Certification; Private Scuba Lessons; Scuba Refresher for Certified Divers; Try Scuba Diving; Enriched Air Diver (Nitrox) This 'neocortex' can be smooth and uninterrupted, but may also be focally interrupted in more aggressive lesions like GCT. Wayne State University, Orthopaedic Surgery, MI, 2007 University of Texas Southwestern Medical School, Surgery, TX, 2002 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. Lippincott Williams & Wilkins. When considering Pagets disease, it is extremely helpful to note whether there is associated bony enlargement. colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. Most commonly encountered bone tumor in the small bones of the hand and foot. A mnemonicfor remembering the causes of diffuse bony sclerosis is: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. 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 ]. Osteosarcoma (2) Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them. Development in centrally located osteochondromas like the pelvis, hip and shoulder is most common. Eosinophilic granuloma like osteomyelitis, can be a serious mimicker of malignancy (particularly Ewing sarcoma). Centrally there is an ill-defined osteolytic area. Chang C, Garner H, Ahlawat S et al. Ali Mohammed Hammamy R, Farooqui K, Ghadban W. Sclerotic Bone Metastasis in Pulmonary Adenocarcinoma. Macedo F, Ladeira K, Pinho F et al. It is nost commonly located on the posterior side of the distal meta-diaphysis of the femur. 3. Bone marrow edema can happen with fractures and other serious bone or joint injuries. Radionuclide bone scan shows a classic "double density" sign of osteoid osteoma located in the tibia: markedly increased radioactivity in the center ( arrow) is related to the nidus, less active areas ( arrowheads) represent reactive sclerosis. Breast cancer (usually mixed lytic/sclerotic), Bone islands do not have edema in the adjacent bone marrow or extension into surrounding soft tissue or adjacent bony destruction. W. B. Saunders company 1995, by Mark J. Kransdorf and Donald E. Sweet (B) In another patient, a 21-year-old woman, note a radiolucent lesion with sclerotic border affecting the medial cortex of the distal femur ( arrows ). Cortical destruction is a common finding, and not very useful in distinguishing between malignant and benign lesions. This feature differentiates it from a juxtacortical tumor. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-22391. 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. Small osteolytic lesion (up to 1.5 cm) with or without central calcification. Differential Diagnosis in Orthopaedic Oncology. Subungual exostoses are bony projections which arise from the dorsal surface of the distal phalanx, most commonly of the hallux. Here are links to other articles about bone tumors: Most bone tumors are osteolytic. Resonance Imaging Saeed M. Bafaraj . 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. The juxtacortical mass has a high SI and lobulated contours. 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). Studies suggest that beyond joint wear and tear . Therefore, MRI and bone scan were performed. They usually affect posterior vertebral elements and their number and size increase with age. Wide zone of transition FIGURE 2.7 Computed tomography of osteoid osteoma. In this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. Imaging is often helpful in determining a diagnosis, and it can sometimes make a particular diagnosis nearly certain. Here a partially calcified mass against the proximal humerus with involvement of the cortical bone on an axial CT image. Generic Differential Diagnosis of Sclerotic Bone Lesions. 7. Guidelines for the Diagnostic Management of Incidental Solitary Bone Lesions on CT and MRI in Adults: Bone Reporting and Data System (Bone-RADS). How should one approach sclerotic bone disease? . DD: Ganglion cyst, osteomyelitis, GCT, ABC, enchondroma. PET features high sensitivity in the detection of bone metastases especially 18 NaF-PET is suitable for the detection of sclerotic metastases since it shows tracer uptake in locations with osteoblastic activity and is more accurate than FDG-PET 3.

Notice that the cortical bone extends into the lesion. 6. Infection is seen in all ages. Focal sclerotic bony lesions (mnemonic). These lesions may have ill-defined margins, but cortical destruction and an aggressive type of periosteal reaction may also be seen. AJR Am J Roentgenol. The images show on the left a typical osteolytic NOF with a sharp sclerotic border. When considering hyperparathyroidism, look for evidence of subperiosteal bone resorption. FD is often purely lytic, but may have a groundglass appearance as the matrix calcifies. This could very well be an enchondroma. Distinction of Long Bone Stress Fractures from Pathologic Fractures on Cross-Sectional Imaging: How Successful Are We? The zone of transition only applies to osteolytic lesions since sclerotic lesions usually have a narrow transition zone. 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. Ulano A, Bredella M, Burke P et al. Most of the time, sclerotic lesions are benign. The bone marrow compartment is not involved which is important for the surgical strategy. These are infections and eosinophilic granuloma. A periosteal chondroma may have the same imaging characteristics, however, these are almost always much smaller. Growth of osteochondroma in skeletally mature patient, Irregular or indistinct surface of lesions, focal lucent regions in interior of lesions, presence of soft tissue mass with scattered or irregular calcifications. At Henry Ford Orthopaedics in Chelsea our mission is to provide personalized treatment plans specific to each patient, to ensure the best possible outcome. Henry Ford Hospital, Neuro Surgery, MI, 1999 Universitat Dusseldorf, Neuro Surgery, 1990 Universitaire Instelling Antwerpen, Neuro Surgery, 1983 W. B. Saunders company 1995, by Mark J. Kransdorf and Donald E. Sweet 2021;13(22):5711. Particularly chronic osteomyelitis may have a sclerotic appearance. Kimura T. Multidisciplinary Approach for Bone Metastasis: A Review. Rib lesions detected on bone scintigraphy often require further characterization with radiography or CT to improve specificity (Figs. Radiology. It is a feature of malignant bone tumors. CT imaging example of the location pattern of sclerotic bone lesions in the skull, spine, and pelvis of TSC patients and control subjects. Differentiating between a diaphyseal and a metaphyseal location is not always possible. As part of the test, a healthcare professional takes a sample of the CSF by Mulder JD et al CT scan is usually very helpful in detecting the nidus and differentiating osteoid osteoma from other sclerotic lesions like osteoblastoma, osteomyelitis, arthritis, stress fracture and enostosis. It classically presents with nocturnal pain in young patients, painful scoliosis, and marked relief from NSAIDs (nonsteroidal anti-inflammatory drugs). Here CT-images of a patient with prostate cancer. Most common malignant bone tumor, which is almost always low-grade, Primary sites of origin: proximal long bones, around knee, pelvis and shoulder girdle, usually central and metaphyseal. Other benign lesions, like solitary bone cyst, fibrous dysplasia, chondroblastoma and other benign bone tumors may become inert and may also become sclerotic. Hall F & Gore S. Osteosclerotic Myeloma Variants. SusanaBoronat, IgnasiBarber, VivekPargaonkar, JoshuaChang, Elizabeth A.Thiele . 33.1b), CT scan axial images (c), and bone scintigraphy (d). 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. 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. Oncol Rev. Here images of an osteosarcoma in the right femur. 2016;207(2):362-8. More heterogenous and irregular with bony trabecular destruction and possible extension beyond the confines of the cortex. Differential Diagnosis of Diffuse Sclerotic Bone Lesions. Calcifications or mineralization within a bone lesion may be an important clue in the differential diagnosis. In skeletally mature patients, GCTs begin in the metaphysics and extend deep to the subchondral bone plate of the articular surface. This is extremely common in Pagets disease but extremely uncommon with a blastic metastasis. 1991;167(9):549-52. Detecting a benign periosteal reaction may be very helpful, since malignant lesions never cause a benign periosteal reaction. (white arrows). The contour of the involved bone is usually normal or with mild expansive remodelling. ( A1,A2) Transversal CT of the skull of a TSC patient and . A periosteal reaction with or without layering may be present. WSI digital slide: https://kikoxp.com/posts/4606. 2nd most common primary bone tumor and highly malignant. 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. Etiology Biopsy revealed dedifferentiated chondrosarcoma. Edema often present in the surrounding bone marrow. Differential diagnosis However, the exact mechanism that leads to osteoblastic formation is not entirely elucidated. Amsterdam: Elsevier; 1993. Sclerotic or osteoblastic bone metastases are distant tumor deposits of a primary tumor within bone characterized by new bone deposition or new bone formation. Prevalence of 3-5% in patients with hereditary multiple osteohondromas. In patients 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. Bone and Joint Imaging. Here an image of a patient with chronic osteomyelitis. Giant cell bone tumors are usually benign (not cancerous) but the malignant form can affect the legs, especially near the knees. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. Distinguishing Untreated Osteoblastic Metastases From Enostoses Using CT Attenuation Measurements. Lets apply the good old universal differential diagnosis to sclerotic bone lesions. Focal sclerotic bony lesions (mnemonic) Last revised by Daniel J Bell on 18 Feb 2019 Edit article Citation, DOI & article data A popular mnemonic to help remember causes of focal sclerotic bony lesions is: HOME LIFE Mnemonic H: healed non-ossifying fibroma (NOF) O: osteoma M: metastasis E: Ewing sarcoma L: lymphoma I: infection or infarct Here a lesion located in the epi- and metaphysis of the proximal humerus. Based on the morphology and the age of the patients, these lesions are benign. Chrondroid tumors are more frequently encountered than bone infarcts. Typical presentation: central lesion in metaphysis or diaphysis with a well defined serpentiginous border. Diffuse bony sclerosis (mnemonic). Therefore, knowing the homogeneously sclerotic bone lesions can be useful, such as enostosis (bone island) (), osteoma (), and callus or bone graft.The plain radiography and CT images of enostosis consist of a circular or oblong area of dense bone with an irregular and speculated margin, which have been . I think that the best way is to start with a good differential diagnosis for sclerotic bones. 33.1a) and sagittal short tau inversion recovery (STIR; Fig. Causes: corticosteroid use, sickle cell disease, trauma, Gaucher's disease, renal transplantation. 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. It is associated with near total fat loss, severe insulin resistance and hypoleptinemia leading to metabolic derangements.Case PresentationWe report a 25- year- old female with 1-Acylglycerol-3-phosphate-O-acyltransferase 2 (APGAT2) mutation, and both sclerotic and lytic bone lesions together for the first time. A benign type of periosteal reaction is a thick, wavy and uniform callus formation resulting from chronic irritation. This is a routine medical imaging report. Top five location of bone tumors in alphabethic order: Aneurysmal Bone Cyst -tibia, femur, fibula, spine, humerusAdamantinoma -tibia shaft, mandibleChondroblastoma -femur, humerus, tibia, tarsal bone (calc), patellaChondromyxoid fibroma - tibia, femur, tarsal bone, phalanx foot, fibulaChondrosarcoma - femur, rib, iliac bone, humerus, tibiaChordoma -sacrococcygeal, spheno-occipital, cervical, lumbar, thoracicEosinophilic Granuloma -femur, skull, iliac bone, rib, vertebraEnchondroma -phalanges of hands and feet, femur, humerus, metacarpals, ribEwing's sarcoma - femur, iliac bone, fibula, rib, tibiaFibrous dysplasia - femur, tibia, rib, skull, humerusGiant Cell Tumor - femur, tibia, fibula, humerus, distal radiusHemangioma - spine, ribs, craniofacial bones, femur, tibiaLymphoma - femur, tibia, humerus, iliac bone, vertebraMetastases - vertebrae, ribs, pelvis, femur, humerusNon Ossifying Fibroma - tibia, femur, fibula, humerusOsteoid osteoma - femur, tibia, spine, tarsal bone, phalanxOsteoblastoma - spine, tarsal bone (calc), femur, tibia, humerusOsteochondroma - femur, humerus, tibia, fibula, pelvisOsteomyelitis - femur, tibia, humerus, fibula, radiusOsteosarcoma -femur, tibia, humerus, fibula, iliac boneSolitary Bone Cyst -proximal humerus, proximal femur, calcaneal bone, iliac bone. In 8 of the 24 patients, 17 of 52 new sclerotic lesions (33%) had showed positive uptake on previous bone scans. Differentiating a bone infarct from an enchondroma or low-grade chondrosarcoma on plain films can be difficult or even impossible. 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. 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. Unable to process the form. 2021;50(5):847-69. The radiograph shows typical bone infarcts in diaphysis and metaphysis of femur and tibia.. On MR imaging bone infarcts are characterized by irregulair serpentiginous margins with low signal intensity on both T1 and T2 WI and with intermediate to high fat signal in the center part. -. For example: Differential Diagnosis of Focal or Multifocal Sclerotic Bone Lesions. Here Melorrheostosis of the ulna with the appearance of candle wax. Osteoblastic bone metastases are characterized by increased bone formation 2. These are inert filled-in non-ossifying fibromas. 13. Mark Blumenkehl, MD is a specialist in Gastroenterology whose practice locations include: Detroit, Sterling Hgts RT @JMGardnerMD: 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. Differentiation of Predominantly Osteoblastic and Osteolytic Spine Metastases by Using Susceptibility-Weighted MRI. mutation, and both sclerotic and lytic bone lesions together for the first time. In this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. The cause of sclerotic lesions was assessed histologically or by clinical and imaging follow-up. Multiple enchondromas are seen in Morbus Ollier. 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. 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. Well, generally, it means that it is due to a fairly slow-growing process. Mixed lytic/sclerotic lesion of right posterolateral 10 th rib, with extensive aggressive-appearing periostitis, as well as a multilobulated soft tissue component. Contact Information and Hours. Here some typical examples of bone tumors in the foot: Fundamentals of Skeletal Radiology, second edition These lesions are not osteochondromas, but consist of reactive cartilage metaplasia.
