A 59-year-old female patient suddenly developed vomiting and gait disturbances followed by decreasing consciousness. CT scans revealed a hemorrhage within the left basal ganglia region with rupture into the ventricles and consecutive hydrocephalus. On angiography an aneurysm in the region of the caput nuclei caudati was shown to be the source of the bleeding. On repeat-angiography 4 months later the aneurysm was no longer visualized, probably due to thrombosis. This is an extraordinary case of a basal ganglia aneurysm comparable with the aneurysms of Willis' circle, but located in a region where generally microaneurysms--mostly combined with hypertension or moyamoya disease--can be found.
一名59岁女性患者突然出现呕吐和步态障碍，随后意识逐渐下降。CT扫描显示左侧基底节区出血并破入脑室，继而出现脑积水。血管造影显示尾状核头部区域的一个动脉瘤是出血来源。4个月后复查血管造影时，动脉瘤未再显影，可能是由于血栓形成。这是一例基底节动脉瘤的特殊病例，与 Willis 环动脉瘤类似，但位于通常可发现微动脉瘤（大多与高血压或烟雾病相关）的区域。
