Case Discussion

Osteochondromas are a relatively common imaging finding, accounting for 10-15% of all bone tumours and 20-50% of all benign bone tumours. Although usually thought of as a benign bone tumour, they may be thought of as a developmental anomaly. They are frequently asymptomatic and have very low malignant potential if sporadic and solitary.
