Case Discussion

Cerebral cavernous venous malformations also named cavernomas or cavernous hemangiomata, which are a vascular abnormality of the central nervous system. They contain blood products at various stages of evolution. The first one is surrounded by perilesional edema owing to the possibility of a recent bleed. They are usually <3 cm in size. The risk of bleed increases with deep brainstem lesions.  Up to 25% of patients present with hemorrhage that can cause headache, followed by neurological symptoms or decreased level of consciousness.
