Enchondroma (proximal tibia)

Case contributed by Dr Aneta Kecler-Pietrzyk

Presentation

Referred by GP with ongoing knee pain, query osteoarthritis. No history of trauma. No prior medical or surgical history.

Patient Data

Age: 55
Gender: Male
X-ray

Incidental finding of well-circumscribed lesion with scalloped margins seen within proximal tibia. Mild spiking of tibial spines. Otherwise no evidence of arthritis. No fracture. 

Case Discussion

The well-defined lesion within the proximal tibia (metaphyseal region) with scalloped margins. The narrow transition zone, lack of periosteal reaction and location favours a benign lesion and the top differential diagnosis is enchondroma with the main differential diagnosis being bone infarct.
