The authors report a case of a distal anterior choroidal artery aneurysm in a 75-year-old female who presented with nausea, vomiting, and severe headache. Computed tomographic (CT) scans revealed a hematoma in the right lateral ventricle and a subarachnoid hemorrhage in the right parasellar-Sylvian cistern. Cerebral angiography showed a saccular aneurysm at the right distal anterior choroidal artery. The authors intended to operate at the chronic stage, and carried out conservative management. After 1 month her condition suddenly worsened and she died, although a CT scan showed no remarkable changes. At autopsy, a pulmonary artery thrombosis was considered the cause of death. The aneurysm was identified in the temporal horn of the right lateral ventricle, and was a true aneurysm.
作者报告了一例75岁女性的远端脉络膜前动脉动脉瘤病例，该患者表现为恶心、呕吐和严重头痛。计算机断层扫描（CT）显示右侧侧脑室有血肿，右侧鞍旁-大脑外侧裂池有蛛网膜下腔出血。脑血管造影显示右侧远端脉络膜前动脉有一个囊状动脉瘤。作者打算在慢性期进行手术，并采取了保守治疗。1个月后，她的病情突然恶化并死亡，尽管CT扫描显示没有明显变化。尸检时，肺动脉血栓形成被认为是死亡原因。动脉瘤位于右侧侧脑室颞角，是一个真性动脉瘤。
