An aneurysm of distal lenticulostriate artery is very rare. The natural course and management of this rare aneurysm are not clear.
An 81-year-old woman developed consciousness disturbance. Computed tomography revealed hemorrhage in the right caudate nucleus and lateral ventricles. Three-dimensional computed tomographic angiography demonstrated only an aneurysm at the basilar artery. On angiography, on the sixth day, an aneurysm at the right lenticulostriate artery was demonstrated. Then, the aneurysm disappeared on three-dimensional computed tomographic angiography on the 15 day. Subsequent radiological examinations revealed no vascular anomaly in the right lenticulostriate artery.
An aneurysm at this location can show dynamic changes based on radiological findings. Close radiological observation is necessary.
豆纹动脉远端动脉瘤非常罕见。这种罕见动脉瘤的自然病程及治疗方法尚不清楚。
一名81岁女性出现意识障碍。计算机断层扫描显示右侧尾状核和侧脑室出血。三维计算机断层血管造影仅显示基底动脉有一个动脉瘤。血管造影显示，在第6天，右侧豆纹动脉有一个动脉瘤。然后，在第15天的三维计算机断层血管造影中，该动脉瘤消失。随后的影像学检查未发现右侧豆纹动脉有血管异常。
该部位的动脉瘤可根据影像学表现呈现动态变化。需要进行密切的影像学观察。
