Abstract

Vasospasm after subarachnoid hemorrhage may alter intracranial hemodynamics. We report a case which showed significant size reduction of an unruptured intracranial aneurysm after resolution of vasospasm. This case may suggest that aneurysm size can be affected by vasospasm, which is presumably related to changes in hemodynamics or spontaneous thrombosis.

Keywords: Cerebral Aneurysm, Subarachnoid Hemorrhage, Intracranial Vasospasm

Fig. 1

Preoperative CT angiography (A) reveals multiple aneurysms (arrows). The right MCA is diffusely narrowed compared with the contralateral side, which suggests vasospasm (arrowheads). Rupture of the aneurysm at the right MCA bifurcation was confirmed intraoperatively. DSA taken on day 10th after operation (B) reveals vasospasm of right MCA and an unruptured aneurysm (arrow) at the origin of the anterior temporal artery. On the follow-up DSA taken three months after the operation (C) shows resolution of vasospasm and significant size reduction of the aneurysm (arrow).

DSA = digital subtraction angiography, MCA = middle cerebral artery
