Secondary synovial chondromatosis in a bursa overlying an osteochondroma mimicking a peripheral chondrosarcoma—a case report

Bursal synovial chondromatosis overlying a solitary osteochondroma of the distal femur: a case report

“…There are only seven case reports of concurrent synovial chondromatosis and an underlying osteochondroma. [8][9][10][11][12][13][14] Bursa formation over the osteochondroma is secondary to mechanical irritation of the osteochondroma and the overlying tendons. Whether the bursal chondromatosis represents a secondary pathology due to the underlying osteochondroma or a true primary benign neoplastic process, is still unclear.…”

“…6,7 There have been few case reports of concomitant existence of osteochondromas and synovial chondromatosis. [8][9][10][11][12][13][14] We report one such case in an 11-year-old female patient and speculate on the common underlying pathogenetic mechanisms which might be involved.…”

Coxa saltans caused by extraarticular synovial chondromatosis overlying an isolated osteochondroma of the greater trochanter: A rare aetiology

“…Peh et al 9 reported a case of secondary synovial chondromatosis within a bursa surrounding osteochondroma of the pubic bone. Errani et al 10 have described a case of synovial chondromatosis within a bursa over osteochondroma arising from lesser trochanter mimicking chondrosarcoma. Brandon et al 11 have reported a case of pes anserinus bursal synovial chondromatosis secondary to osteochondroma.…”

Osteocondroma: diagnóstico radiológico, complicaciones y variantes

“…La bursa, a su vez, puede complicarse, pudiendo producirse infección, inflamación, o hemorragia (1) ; la presencia de un bultoma debido a una bursa infectada reactiva puede sugerir clíncamente la malignización de una lesión (30) , En este aspecto, la RM es un excelente método de imagen que permite hacer el diagnóstico demostrando el realce periférico con contraste o la presencia de tabiques en el casos de sobreinfección (Figura 12 a-c) (30) . Otro aspecto a tener en cuenta es la presencia de una condrometaplasia que derive en una osteocondromatosis secundaria a partir de la sinovial de la bursa (1,31) . Malignización:…”
