回复：Please help! distal femoral slcerotic lesion, no idea what it is.

Thank to everyone who responsed. The mainstay of opinions was old/choronic infarction, other opinions included benign calcified endochondroma, desmoplatic fibroma, chondrosarcoma, chondromixoid fibroma,liposclerosing myxofibrous tumor. The powerpoint attached in original email  provided more details including X-ray and  more MRI images. The pathologic dignosis was consistent with osteoma. The surgeon said the lesion was very hard.

Best,
Xianjing
