Computed tomography (CT) scan of the brain revealed a thick subarachnoid hemorrhage with intraventricular extension (Fisher group III) and mild hydrocephalus (Fig. 1).
Three-dimensional computed tomography angiogram on admission revealed an irregularly shaped saccular aneurysm at the bifurcation of left A2 and frontopolar artery (arrows). No apparent spasm of the right middle cerebral artery was seen.

An irregularly shaped saccular aneurysm was also detected at the bifurcation of the left A2 and the frontopolar artery on three-dimensional computed tomography (3D-CT) angiography (Fig. 2).
A: Computed tomography (CT) scans immediately after the first operation demonstrating the emerging right sylvian subpial hematoma. B: CT scans 12 h after the first operation showing no apparent changes in size or shape of the hematoma. C: CT scans 36 h after the first operation. The sylvian hematoma was definitely enlarged compared with A and B. There was also a left frontal subpial hematoma, which had already been noted, on admission. D: Postoperative CT scans immediately after removal of the hematoma.

CT performed 12 h after surgery showed no change (Fig. 3).
