Info

Rounded lesion has extensive hemosiderin staining and surrounding edema. Features are those of a cavernoma. 

Case Discussion

Features are fairly typical of a large cavernous venous abnormality (a.k.a. cavernoma) and edema would be expected to regress. Unfortunately no follow up is available.
