Abstract
Primary synovial chondromatosis represents a relatively rare benign neoplastic process which shows hyaline cartilage nodules in the subsynovial tissue of a joint, tendon sheath, or bursa. It commonly occurs within joints. The most frequently affected articulation is the knee. Other commonly involved joints include the hip, elbow, shoulder, and ankle. Single giant synovial osteochondroma is furthermore rare entity as in this case which has a history of old trauma. Plain radiograph was done for the patient initially, with contrast enhanced computed tomography (CECT) and magnetic resonance imaging (MRI) done for detailed evaluation. Plain radiograph revealed a calcified lesion inrelation to the olecranon fossa towards the posterior elbow joint. CT scan showed a solitary large ossified lesion separate from the bones in relation to the elbow joint. MRI images showed lesion within the elbow joint with iso-intensity with medulla. Patient underwent surgery and histopathological examination confirmed synovial osteochondromatosis. This case highlights a uncommon presentation of a rare disorder with the formation of a giant synovial osteochondroma.
