Cavernoma of the midbrain

Case contributed by Dr M Shebl

Patient Data

Gender: Male
Modality: MRI

A rounded lesion with peripheral signal drop-out consistent with hemosiderin is seen in left side of midbrain. Centrally the lesion is heterogeneous in signal with regions of high signal on both T1 and T2 weighted images. There is no peripheral oedema and no evidence of hydrocephalus. 

Features are characteristic of a midbrain cavernous malformation.

Case Discussion

cerebral cavernous haemangioma is a common type of cerebral vascular malformation. MRI is the modality of choice, demonstrating a characteristic “popcorn” or "berry" appearance with a rim of signal loss due to haemosiderin
