title: [Early angio-computer tomography of ruptured cerebral aneurysms in subarachnoid hemorrhage].
abstract: In acute subarachnoid hemorrhage a ruptured cerebral aneurysm can be detected by Computed Angiotomography (Angio-CT). In a hyperdense cistern by extravasal blood, a round low-density defect on plain CT which turns into high-density nodular mass with afferent and efferent arteries, is an important finding of ruptured aneurysm. The inverting-density cisternal defect in connection with cerebral arteries is essential for the direct and early Angio-CT diagnosis of ruptured aneurysm.
