Computed Tomography of Cerebral Venous Angiomas

Abstract

Six human cases of venous angioma of the brain, a rare vascular malformation, were studied by computed tomography (CT), angiography and other tests. In each case, angiography demonstrated the typical normal arterial phase and the network of abnormal veins that converge on a single large draining vein. In 3 cases, the CT scans showed rounded areas of high density not unlike neoplasms in appearance. In other cases, the CT scan demonstrated the enlarged draining vein only. The CT scan findings, although not specific, may alert the radiologist to the possibility of this lesion and may lead to its demonstration through angiography.
