This case isDifferentiating between an example of a large chondroid lesion with appearances in keeping with an enchondroma but features whichvs low-grade chondrosarcoma can be challenging 1. Features that should raise the suspicion of low-grade chondrosarcoma include a low grade chondrosarcoma (size >5size over 5-6cm, pain, and endosteal scalloping).

13cm chondroid lesion within the medulla of the distal femoral diametaphysis. No associated soft-tissue component, although partially imaged on the lateral projection.
