What does it mean that a lesion is sclerotic? These lesions usually regress spontaneously and may then become sclerotic. Ulano A, Bredella M, Burke P et al. 2014;71(1):39. Distinction of Long Bone Stress Fractures from Pathologic Fractures on Cross-Sectional Imaging: How Successful Are We? When you are considering osteonecrosis in your differential diagnosis, look at the joints carefully. Symptoms are usually absent, however, in adult patients with a chondroid lesion in a long bone, particularly of larger size, always consider low-grade chondrosarcoma. The chondroid matrix is of a variable amount from almost absent to dens compact chondroid matrix. Benign lesion consisting of well-differentiated mature bone tissue within the medullary cavity. Sclerotic or osteoblastic bone metastases are distant tumor deposits of a primary tumor within bone characterized by new bone deposition or new bone formation. You can then customize the above differential for whichever pattern of sclerosis that you see. Brant WE, Helms CA. The mean and maximum attenuation were measured in Hounsfield units. Bker S, Adams L, Bender Y et al. Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. Here an illustration of the most common sclerotic bone tumors. Here two patients with a bizar parosteal osteochondromatous proliferation (BPOP), also called Nora's lesion. 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). 3. ImageBenign periosteal reaction in an osteoid osteoma.Large arrow indicates solid periosteal reaction.Small arrow indicates nidus. Rib lesions detected on bone scintigraphy often require further characterization with radiography or CT to improve specificity (Figs. This solitary, uniformly high-density lesion with neither edema in the surrounding bone marrow nor extension into the surrounding soft tissue most likely represents a giant bone island. 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. 6. Consider progression of osteohondroma to chondrosarcoma when cartilage cap measures > 10 mm. Rapid growth of the mineralized mass is not uncommon. Sclerotic metastases arise from . 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. The major part of the lesion consists of reactive sclerosis. 2016;207(2):362-8. This occurs in early knee osteoarthritis and indicates the potential for cartilage loss and misalignment of a knee compartment. 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. 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. None of the patients had undergone prior treatment for the metastases. Peripheral chondrosarcoma, arising from an osteochondroma (exostosis). Another finding classic for Pagets disease is that it almost always starts at one end of a bone and then spreads toward the other end of the bone. Sclerosis is usually the most prominent finding in subacute and chronic osteomyelitis. For those that are possibly cancerous, a biopsy is conducted to identify it. In most cases of osteoid osteoma the radiographic appearance is determined by the reactive sclerosis. 1 When the vertebral lesion has no benign features, especially in the older adult patient, metastatic disease is always a significant consideration. Regarding bone disease in SM, increased sBT levels have been 493 associated with both bone sclerosis (due to unknown mechanisms) (8, 18, 19) and 494 osteoporosis (it has been hypothesized that tryptase could induce the production of 495 OPG (61)) (4, 17). Results: In 24 patients, 52 new sclerotic lesions observed during therapy were selected for re-evaluation of conventional radiographs and bone scans. 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. 4. 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. The differential diagnosis of solitary sclerotic bone lesions can be narrowed down according to the following factors 1-3: cartilaginous matrix (rings and arcs appearance). In general, they're slow-growing.. 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. Not infrequently encountered as coincidental finding at later age. Logistic regression analyses were used to assess the association of joint form and lesions on imaging for axSpA patients and controls. Sarcoidosis is a multi-system disease with a range of . Presentation: pain, mass, pathologic fracture. Spinal lesions are commonly spotted on imaging tests. 5. However, not all epidermal inclusion cysts involve bone, and some are confined to the subcutaneous tissues. Enhancement after i.v. 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. Oncol Rev. 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. 12. Unable to process the form. Infection is seen in all ages. 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. T2-weighted MR image reveals a lobulated mass with high signal intensity. Mixed lytic and sclerotic bone metastases are characterized by the presence of both components, that is areas of bone destruction and areas of increased bone formation within one metastatic tumor deposit or one primary tumor that features both kinds of bone metastases, namely osteolytic and osteoblastic metastases 1. The differential for multifocal lesions happens to be identical to that for focal lesions. 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 Mnemonic for multiple oseolytic lesions: FEEMHI: O'Sullivan G, Carty F, Cronin C. Imaging of Bone Metastasis: An Update. Notice that CT depicts these lesions far better (red arrows). The diagnosis is usually established by a combination of imaging and the known presence of a primary tumor that is associated with sclerotic bone metastases. Paget disease is a chronic disorder of unknown origin with increased breakdown of bone and formation of disorganized new bone. 2015;7(8):202-11. Even though plain X-ray and CT would typically be used to follow a suspected bone island, MRI was chosen as the follow-up modality because the sacrum is an area not well seen on plain films due to overlying bowel gas and concern regarding radiation dose from multiple CT scans to the pelvis of a 30-year-old woman. 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. Imaging: Purpose: 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. An ill-defined border with a broad zone of transition is a sign of aggressive growth (1). Ask the patient or the clinician about this. Check for errors and try again. Generally, this just follows common sense some lesions should logically be expected to be focal, others multifocal, and yet others diffuse or systemic. Moreover, questions such as the . RT @JMGardnerMD: 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. 2003;415(415 Suppl):S4-13. We provide care in several areas of orthopedics, such as: hand and wrist care, foot and ankle care, and joint replacement. Imaging is often helpful in determining a diagnosis, and it can sometimes make a particular diagnosis nearly certain. A sclerotic border especially indicates poor biological activity. and PD-L1 PET/CT (PD-L1 positivity is defined as having at least one lesion with radiotracer uptake over the . 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. Despite their remarkable clinical success, the low degradation rate of these materials hampers a broader clinical use. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Causes include trauma, infection, autoimmune diseases, inflammatory diseases, spinal degeneration, congenital malformations, and benign or cancerous tumors. Skeletal Radiol. Home. Aggressive periosteal reaction If there are multiple or polyostotic lesions, the differential diagnosis must be adjusted. 5 Biopsy should be considered in atypical cases or in high-risk patients with primary malignancies associated with osteoblastic metastatic disease. 1, The classic bone island has a spiculated or paintbrush border and is much denser on CT than a osteoblastic metastasis. In this paper, we review the recent years of literature on deep learning-based multiple-lesion recognition. MRI features high sensitivity and high specificity for the demonstration of bone metastases in general and for assessing the bone marrow 2,3. 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. Strahlenther Onkol. 14. AJR 2000; 175:261-263. The diagnosis was fibrous dysplasia. Fundamentals of diagnostic radiology. It is assumed that several tumor-derived growth factors increase osteoblast activity while osteoclast activity is restricted 3,4. The benign type is seen in benign lesions such as benign tumors and following trauma. Secondary bone cancer is much more common than primary bone . Enchondroma, the most commonly encountered lesion of the phalanges. In this article we will discuss a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. Chrondroid tumors are more frequently encountered than bone infarcts. The differential diagnosis mostly depends on the age of the patient and the findings on the conventional radiographs. A periosteal reaction with or without layering may be present. These tumors may be accompanied by a large soft tissue mass while there is almost no visible bone destruction. It could be blood or fluids released from fibrosis (scarred tissue) or necrosis (tissue death). Endosteal scalloping of the cortical bone can be seen in benign lesions like Fybrous dysplasia and low-grade chondrosarcoma. 1989. Contrast-enhanced T1-weighted MR image demonstrates heterogeneous enhancement of the mass with extensive surrounding edema. 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. Click here for more examples of chondroblastoma. Osteosarcoma, chondrosarcoma, and Ewing's sarcoma are the most common types of bone cancer. The term bone infarction is used for osteonecrosis within the diaphysis or metaphysis. 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. Many lesions can be located in both or move from the metaphysis to the diaphysis during growth. Donald Resnick, Mark J. Kransdorf. Here on a radiograph the typical calcifications in the chondroid matrix of an enchondroma. At Henry Ford Orthopaedics in Chelsea our mission is to provide personalized treatment plans specific to each patient, to ensure the best possible outcome. The X-ray features were divided into two groups according to typical and atypical skeletal lesions. The location of a bone lesion within the skeleton can be a clue in the differential diagnosis. <-Lucent Lesions of Bone | Periosteal Reaction->. In breast cancer, metastases may present as lytic lesions that may become sclerotic expressing a favourable response to chemotherapy. Radiologic Atlas of Bone Tumors There are no calcifications. Osteoblastic metastatic disease (see Table 33.1): More often multiple with increased uptake on bone scan. Bone cyst is one of the manifestations of CGL with AGPAT2 mutation. 2019;15:100205. In this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. Isaac A, Dalili D, Dalili D, Weber M. State-Of-The-Art Imaging for Diagnosis of Metastatic Bone Disease. Bone metastases start with the tropism of cancer cells to the bone through different multi-step tumor-host interactions, as described by the . This feature differentiates it from a juxtacortical tumor. A brain MRI can . Coronal T1W image shows lobulated margins and peripheral low SI due to the calcifications. 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. Age: most commonly seen in 10-25 years, but may occur in older patients. Osteoblastic metastases (2) 1. 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. Sclerosis can also be reactive, e.g. Publicationdate 2010-04-10 / update 2022-03-17. Bone marrow edema can happen with fractures and other serious bone or joint injuries. This is opposed to myositis ossificans which may present very close to the cortical bone, but maturation develops from the center to the periphery. It can also be proven histologically. 2021;50(5):847-69. Here are links to other articles about bone tumors: Most bone tumors are osteolytic. AJR Am J Roentgenol. Melorrheostosis is a dysplasia of the bone, characterized by apposition of mature bone on the outer or inner surface of cortical bone. Multiple myeloma is a hematologic malignancy of plasma cells that causes bone-destructive lesions and associated skeletal-related events (SREs). Multiple enchondromas and hemangiomas are seen in Maffucci's syndrome. This could be an osteoblastic metastasis or an osteolytic metastasis that responded to chemotherapy. Other benign lesions, like solitary bone cyst, fibrous dysplasia, chondroblastoma and other benign bone tumors may become inert and may also become sclerotic. Location within the skeleton by Mulder JD, et al. BallooningBallooning is a special type of cortical destruction.In ballooning the destruction of endosteal cortical bone and the addition of new bone on the outside occur at the same rate, resulting in expansion. Differentiating a bone infarct from an enchondroma or low-grade chondrosarcoma on plain films can be difficult or even impossible. Bone scintigraphy can be either negative or show limited uptake. Based on the morphology and the age of the patients, these lesions are benign. UW Radiology Sclerotic Lesions of Bone <-Lucent Lesions of Bone | Periosteal Reaction-> What does it mean that a lesion is sclerotic? 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 Edema often present in the surrounding bone marrow. Notice the numerous predominantly osteoblastic metastases. 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. Osteosarcoma (2) Fundamentals of diagnostic radiology. Chang C, Garner H, Ahlawat S et al. This image is of a 20 year old patient with a sclerotic expansile lesion in the clavicle. SWI:low signal intensity on the inverted magnitude and phase images 9. 2010;35(22):E1221-9. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-8429. 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. Here an image of a patient with chronic osteomyelitis. Sclerotic bone lesions appear exclusively in middle aged black patients. In patients > 30 years, and particularly > 40 years, despite benign radiographic features, a metastasis or plasmacytoma also have to be considered Another approach to the differential diagnosis of sclerotic bone lesions is to use the mnemonic I VINDICATE, which means 'I clear myself from accusation'. Guidelines for the Diagnostic Management of Incidental Solitary Bone Lesions on CT and MRI in Adults: Bone Reporting and Data System (Bone-RADS). The contour of the involved bone is usually normal or with mild expansive remodelling. Prevalence of 3-5% in patients with hereditary multiple osteohondromas. Parkinson's disease, multiple sclerosis, brain tumors and brain trauma [2]. 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. This proved to be a reactive calcification secondary to trauma. 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. Growth of osteochondromas at adult ages, which is characterized by a thick cartilaginous cap (high SI on T2WI) should raise the suspicion of progression to a peripheral chondrosarcoma. 7. Development in centrally located osteochondromas like the pelvis, hip and shoulder is most common. The MR image shows that the lesion has lobulated contours and nodular enhancement. Notice the numerous ill-defined osteoblastic metastases. {"url":"/signup-modal-props.json?lang=us"}, Yap K, Knipe H, Niknejad M, et al. Axial imaging for differentiation from Brodie abscess, osteoblastoma, stress fracture. Incidentally discovered, benign lesions also called enostoses, which are islands of cortical bone located in the cancellous bone. Differential diagnosis . Notice that there are small areas of ill-defined osteolysis. After an injury, different types of fluid can build up in a bone. If the osteonecrosis is located in the epiphysis, the term avascular osteonecrosis is used. 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. Sclerosis is present from either tumor new bone formation or reactive sclerosis. Many sclerotic lesions in patients > 20 years are healed, previously osteolytic lesions which have ossified, such as: NOF, EG, SBC, ABC and chondroblastoma. In juxta-articular localisation, the reactive sclerosis may be absent. SusanaBoronat, IgnasiBarber, VivekPargaonkar, JoshuaChang, Elizabeth A.Thiele . Cortical destruction is a common finding, and not very useful in distinguishing between malignant and benign lesions. They usually affect posterior vertebral elements and their number and size increase with age. DD: juxtacortical chondrosarcoma, parosteal osteosarcoma. Central location most common with some expansion and cortical thinning. Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them. In the subchondral bone, the number of TRAP-positive cells peaked on day 14. Parosteal osteosarcoma is a sarcoma that has it's origin on the surface of the bone. Physical examination and past medical history were normal and noncontributory respectively. However, the exact mechanism that leads to osteoblastic formation is not entirely elucidated. Imaging of skull vault tumors in adults: Author: Pons Escoda, Albert Naval Baudin, Pablo . Complete envelopment may occur. Sclerotic osteoblastic metastases must be included in the differential diagnosis of any sclerotic bone lesion in a patient > 40 years. Cancers (Basel). Matching the degradation rate of the materials with neo bone formation remains a challenge for bone-repairing materials. It is nost commonly located on the posterior side of the distal meta-diaphysis of the femur. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. CT 2. Halo of increased signal on T2 W images about the low signal central lesion is suggestive of metastatic disease. 2021;13(22):5711. It is barely visible within the bone, but an agressive periostitis is seen (arrow). Fibrous dysplasia and eosinophilic granuloma more commonly present as osteolytic lesions, but they can be sclerotic. Polyostotic lesions > 30 years Bone metastases have a predilection for hematopoietic marrow sites: spine, pelvis, ribs, cranium and proximal long bones: femur, humerus. 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. The homogeneous pattern is relatively uncommon compared to the heterogeneous pattern. 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. Our patient had lytic bone lesions in (femur) long bones and also sclerotic lesions in the pelvic which was . In some locations, such as in the humerus or around the knee, almost all bone tumors may be found. -. A high grade chondrosarcoma must be considered in the differential diagnosis. Notice the homogeneous thickening of the cortical bone. For example: Differential Diagnosis of Focal or Multifocal Sclerotic Bone Lesions. Osteoma consists of densely compact bone. The bone scan is also helpful to look for additional sites of increased uptake that may not have been imaged, such as multiple nontraumatic rib, calvarial, or long bone lesions, which would strongly suggest the diagnosis of metastatic disease.
