Chondromyxoid Fibroma
-Chondromyxoid Fibroma is a rare lesion.
-CMF resembles NOF.
-Preferential sites: proximal tibia and foot.
- Although the name suggests that CMF is a chondroid lesion, calcifications are usually not seen. On the above images of a CMF.
- There is an eccentric osteolytic lesion in the metaphysis of the proximal tibia. On the inner side there is a sclerotic margin. On the outer side there is a regular cortical destruction with peripheral bone layer.
-The MR also shows a sclerotic margin with low signal intensity
-Discriminators : Mention when an NOF is mentioned.
