Computed tomography of cerebral venous angiomas

Abstract

Six cases of venous angioma of the brain, a rare vascular malformation, were studied by means of 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 three cases, the CT scans showed rounded areas of high density not unlike neoplasms in appearance. In the 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.
