Cerebellar venous angiomas. A continuing controversy.
We have studied three patients with angiographically documented cerebellar venous angioma (CVA). One patient had a subacute cerebellar hematoma and underwent posterior fossa craniotomy for evacuation of the hematoma and excision of the malformation. A hemorrhagic venous infarction of the brain stem and cerebellum occurred, and the patient died three weeks postoperatively. A second patient with an unruptured CVA had a history of headaches, tinnitus, and vertigo. Conservative treatment was elected, and the patient's condition remains unchanged after 11 months of follow-up. The third patient, recently diagnosed as having an unruptured CVA had episodic vertigo and disequilibrium. Conservative treatment was chosen, and he is asymptomatic after six months of follow-up. Based on a review of 24 other cases of CVA plus our experience we could not conclude any definite trend regarding natural history or treatment. However, conservative treatment seems the logical choice in patients with unruptured CVA.
