Perforating arteries are thin and long vessels which originate from the main cerebral arteries. Subarachnoidal hemorrhage from a perforator aneurysm is rare. Here, we report on a 70-year-old woman who presented with severe subarachnoid hemorrhage from a fusiform lateral anterior (A1) artery perforator aneurysm. Unexpectedly, digital subtraction angiography was non-diagnostic. MR imaging, however, demonstrated occlusion of the aneurysm secondary to thrombosis. Surgery was performed to remove the associated hematoma, and histopathological examination verified intraaneurysmal thrombosis.
穿支动脉是起源于大脑主要动脉的细长血管。穿支动脉瘤引起的蛛网膜下腔出血很少见。在此，我们报告一名70岁女性，她因梭形外侧前（A1）动脉穿支动脉瘤出现严重蛛网膜下腔出血。出乎意料的是，数字减影血管造影未明确诊断。然而，磁共振成像显示动脉瘤因血栓形成而闭塞。进行了手术以清除相关血肿，组织病理学检查证实动脉瘤内有血栓形成。
