What are your findings?
Long heterogeneously intermediate T1 signal and heterogeneously high T2 signal lesion within the distal femoral diaphysis extending into the metaphysis. Evidence of minor endosteal scalloping affecting the posterior cortex of the femoral metaphysis.
What features should raise the suspicion of a low-grade chondrosarcoma?
Size over 5-6cm, pain, and endosteal scalloping.
Long 13.5x2.2x1.9cm (CCxTRxAP) heterogeneously intermediate T1 signal and heterogeneously high T2 signal lesion within the distal femoral diaphysis extending into the metaphysis. Evidence of minor endosteal scalloping affecting the posterior cortex of the femoral metaphysis.
