Regarding the imaging findings (x-ray is not accessible), metatarsal osteochondroma is suspected Osteochondromas are a relatively common imaging finding, accounting for 10-15% of all bone tumors and approximately 35% of all benign bone tumors. Although usually thought of as a benign bone tumor, they may be thought of as a developmental anomaly. They are frequently asymptomatic and have very low malignant potential if sporadic and solitary Osteochondroma of the 5th metatarsal. Case contributed by Assoc Prof Frank Gaillard . Diagnosis certain. Diagnosis certain. From the case: Osteochondroma of the 5th metatarsal. X-ray. Loading Stack - The radiographic presentation of an osteochondroma is a lesion that protrudes from the host bone on a sessile or pedunculated bony stalk and points away from the adjacent joint. The cortex and spongiosa of the osteochondroma blend imperceptibly with the cortex and spongiosa of the host bone (Fig. 5). This is its key radiologic feature.

Osteochondroma - metatarsal Radiology Case Radiopaedia

Enchondroma. Enchondromas, also known as chondromas 7 , are relatively common intramedullary cartilage neoplasms with benign imaging features. They share histologic features with low-grade chondrosarcoma, and are sometimes classified under the umbrella term low-grade chondral series tumors. Enchondromas account for the 'E' in the popular. Diagnosis of secondary chondrosarcoma arising in osteochondroma can be challenging and requires correlation with clinical and imaging findings ( Mod Pathol 2012;25:1275, Radiology 2010;255:857, Oncogene 2012;31:1095 ) Tumor growth and thickening of the cartilage cap (usually > 2 cm) are suggestive of malignant transformation in skeletally. The term bone infarction is used for osteonecrosis within the diaphysis or metaphysis. If the osteonecrosis is located in the epiphysis, the term avascular osteonecrosis is used. The radiograph shows typical bone infarcts in diaphysis and metaphysis of femur and tibia

  1. With both benign and malignant primary tumors, the metatarsal bones were most commonly affected, followed by the calcaneus. The most common benign tumor was giant cell tumor, followed by chondromyxoid fibroma and osteochondroma. The most common malignant primary bone tumors were (in decreasing order) chondrosarcoma, osteosarcoma, and Ewing sarcoma
  2. Exostoses are defined as benign growths of bone extending outwards from the surface of a bone. It can occur in any bone and be triggered by a number of factors. There are a number of examples of exostoses that occur due to local irritant stimuli: ivory exostosis. exostosis of the external auditory canal (surfer's ear
  3. Osteochondroma An osteochondroma (osteocartilaginous exostosis) is a benign osseous outgrowth from the cortex of bone with a cartilaginous cap. It accounts for less than 15% of all hand tumors, occurring more commonly in the phalanges than the metacarpals
  4. Osteochondroma is a bony protrusion covered by a cartilaginous cap. Growth of the osteochondroma takes place in the cap, corresponding with normal enchondral growth at the growth plates. Accordingly, growth of osteochondromas is allowed until a patient reaches adulthood and the physeal plates are closed
  5. In cases of juxtacortical osteoma, it is crucial to differentiate between this type of tumor and parosteal osteosarcoma, sessile osteochondroma, and matured juxtacortical focus of myositis ossificans (2, 3, 5). We describe a case of an osteoma arising from the second metatarsal bone, a rare anatomical location for osteoma

PMID: 6863809 [Indexed for MEDLINE] Publication Types Osteochondromas are benign osseous neoplasms with a distinct hyaline cartilage cap originating from the physis, and they cease to grow with skeletal maturity On gross examination, an osteochondroma is an irregular bony mass with a bluish gray cap of cartilage. Opaque yellow cartilage has calcification within the matrix. The base of the lesion has a rim of cortical bone and central cancellous bone. Occasionally, a bursae develops over an osteochondroma The radiographic appearance of osteochondroma is virtually pathognomonic, presenting as a sessile or pedunculated osseous growth in continuity with the underlying cortex and medullary cavity of the parent bone (13). In long bones, they appear to emanate from the metaphyseal region and display a cauliflower-like appearance Osteochondromas occur in any long bones that undergoendochondral ossification. The lesions usually begingrowing at the growth plate and are most frequently found Pediatric Radiologist, Phoenix Children's Hospital, Mesa, AZ

Occasionally, entrapment may be seen as a complication of hallux valgus repair. Patients may present with pain, tingling, numbness, and paresthesias along the medial and plantar aspects of the first metatarsal shaft and the first metatarsophalangeal joint. At clinical examination, there is a palpable mass medioplantar to the distal first. Solitary osteochondroma is the most common bone tumor, accounting for 20% to 50% of all benign bony tumors. Osteochondromas are usually found on the metaphysis of the long bones near the physis; the bones of the foot are less commonly involved.

Peripheral entrapment neuropathies are an important cause of pain and functional impairment in the lower extremity ().Until recently, the mainstay of diagnosis was clinical examination and electrophysiologic evaluation ().Because of the variable anatomy of the nerves and the muscles they supply, the clinical diagnosis is not always reliable () In contrast, few cases of metatarsal osteochondroma have been reported in adolescents. Dorfman and Osler reported a solitary metatarsal osteochondroma in a 16-year-old male who was treated surgically with a satisfactory outcome. A case of an osteochondroma with an unusual talar location was reported in a 6-year-old male by Boya et al . We found.

Osteochondroma (leg, hip, shoulder) Osteochondroma is the most common type of noncancerous growth on the bones. It usually has no symptoms, but it may cause other complications The enchondroma lesion itself is made up of a benign growth of hyaline cartilage. Its exact cause is unknown. It displays equal prevalence in males and females between ages 20 and 50, when it is often discovered, although enchondroma lesions may begin to grow in early childhood. There is no sex predilection, and since most enchondromas are.

Enchondromas. Enchondromas are benign chondrogenic tumors composed of hyaline cartilage that typically occur in medullary cavity of the diaphysis or metaphysis, most commonly in the hands. Patients typically present between the ages of 20-50 with an asymptomatic lesion, discovered incidentally on radiographs Exostoses of the metatarsal bones (splints) are common and may or may not be associated with lameness. Splint exostoses may be caused by direct trauma or instability between metatarsal bones. Large exostoses on the proximal lateral aspect of the second or fourth metatarsal bones are common and usually asymptomatic Common causes of cortically based sclerosis and thickening on radiographs include osteoid osteoma, chronic infection, and stress fracture. These entities often have a similar appearance on radiographs but can typically be differentiated on CT. On the rare occasion when the CT appearance of the sclerotic lesion remains nonspecific, MRI or a. We report a case of a lumbar spinal osteochondroma that transformed into a large chondrosarcoma in a 39-year-old male who presented with an abdominal mass and back pain. This mass was also associated with a fracture of the stalk, which on cross-sectional imaging mimicked a mass of retroperitoneal origin. The diagnosis of chondrosarcoma transforming from a lumbar osteochondroma became apparent. Practice Essentials. Osteochondrosis is a self-limiting developmental derangement of normal bone growth, primarily involving the centers of ossification in the epiphysis. [ 1, 2] It usually begins in childhood as a degenerative or necrotic condition. By definition, osteochondrosis is an aseptic ischemic necrosis
