CT and MRI features characteristic of chondrosarcoma, histologically-proven as conventional chondrosarcoma grade I according to O'Neal and Ackermann classification

Conventional chondrosarcoma, also known as central chondrosarcoma, is considered as the most common subtype of chondrosarcoma. It may be of low, intermediate or high grade. The low-grade conventional chondrosarcomas (as in this case) can be difficult to differentiate from an enchondroma.
