That contrast enhancement pattern suggests chondromyxoid fibroma.

Hi !!
Thank you everyone for the comments.Of aggressive calcaneal lesions, the 2 most common are Chondrosarcoma and Ewing (in the right age group)…synovial sarcoma also has a predilection for the foot, but that is typically soft tissue.If this is not a complex cyst somehow secondary to peroneal pathology, it is probably chondrosarcoma. So at this age you can consider Clear Cell Chondrosarcoma….peak age is in the 30s…but I believe it is still more common to have conventional chondrosarcoma at any age, since clear cell is rare.

Hi, I think you’re right about chondrosarcoma. There was a big british series of calcaneal lesions 3 yr ago, in which CS was rare, they had a few chondroblastomas but i read that cb kept to epiphyseal-equivalent calcaneal locations with lots of surrounding edema. https://pmc.ncbi.nlm.nih.gov/articles/PMC8553183/

Any XR or CT? Looks chondroid, agree. Sonin Andrew.
I’d definitely be considering a chondroma given the imaging findings. There is narrow zone of transition posteriorly and ill defined anterior. Although the lesion is expansile, the cortex is not eroded. Whether that’s attributing to the soft tissue inflammation is a possibility. No definite soft tissue mass component that can be appreciated either. M N.
It is a cartilage tumor. Unusual site and there is likely infiltration – so chondrosarcoma.

How did this patient present? I’ll play devils advocate and say favored to be benign IF this is incidental. I’ve seen plenty of variations of intraosseous ganglia with enhancing granulation along the margins possible early transformation into a lipoma. Certainly on the far edge of the spectrum. If no pain I’d VERY closely follow it but wouldn’t argue with bx either. Cina Joseph Ali
Kind regards.
