Patient Data

Age: 50 years

A large right-sided hemorrhagic lesion is present without abnormal enhancement of abnormal vessels. Perilesional edema is noted. Associated mass effect is mild.


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.
