title: Cerebral venous angioma: computerized tomography and angiographic diagnosis.
abstract: Four cases of cerebral venous angioma were studied by both CT and angiography. All cases showed similar angiographic findings: a normal arterial phase and a local network of small veins that converged centrally into a single large draining vein. However, CT showed nodular areas of high density in three cases, and a curvilinear enhanced lesion representing the draining vein in the other. CT findings are nonspecific but very useful for detecting the lesion and demonstrating the associated hematoma. Angiographic findings are not so obvious as in AVM, but are necessary for the final diagnosis of the venous angioma.
