Consideration of the operative indications for posterior fossa venous angiomas.

The case of a patient with a venous angioma located in the midline of the posterior fossa and responsible for a cerebellar hemorrhage is reported. The patient had a good recovery after removal of the hematoma. We reviewed this and seven other cases of venous angioma in the posterior fossa reported in the literature. It appears that those venous angiomas that occur in the cerebellar hemisphere and produce a cerebellar hematoma can be successfully removed.
