We performed three-dimensional computed tomography (3D-CT) in 6 patients of cerebral aneurysm. Prior cerebral angiography showed a total of 17 aneurysms. 3D-CT alone detected 10 cerebral aneurysm (59%) . It was possible to identify aneurysms lager than 10 mm even when located near the circle of Willis. It was difficult to identify aneurysms when smaller than 7 mm regardless of their location. 3D-CT was of limited value in detecting cerebral aneurysms, particularly when located near the circle of Willis with complex vascular network. As cases of oculomotor palsy may be caused by lesions other than cerebral aneurysm, we advocate that 3D-CT be performed after magnetic resonance imaging (MRI) in screening cases of suspected cerebral aneurysm.
