title: Cerebral venous angioma: correlation of radionuclide brain scan, transmission computed tomography, and angiography.
abstract: Three cases of intracerebral venous angioma, a rare vascular malformation, were studied by radionuclide brain scan, transmission computed tomography (TCT) and angiography. In each case, the radionuclide flow study demonstrated a typical area of abnormal increase in activity during the venous phase; in two of the cases the arterial phase was also abnormal. Each contrast angiogram demonstrated a normal arterial distribution and a characteristic network of abnormal veins that converged to a large transcerebral draining vein. The TCT scans showed enhancing, curvilinear densities; while not specific, this finding should suggest the possibility of venous angioma in the brain.
