Extraarticular extrasynovial solitary osteochondromatosis of the ankle: A rare case report and review of literature

Abstract

Highlights Extra articular osteochondromatosis is rare and scarcely reported around the ankle joint. Due to the subtle clinical and radiological presentation of SC they often lead to a diagnostic challenge. Higher degree of suspicion enables early diagnosis, thereby preventing both morbidity and inadequate treatment. Although MRI plays a key role in deciding the extent of the surgery, confirmation can be made only with histopathology. Long term follow up is mandatory considering both the risk of local recurrence and rare malignant transformation.
