A 10-year-old girl presented with a 6-week history of gradually increasing, abnormal movements and weakness of the right upper and lower limbs. There were no features of raised intracranial pressure. Computed tomography scan and magnetic resonance imaging (MRI) of the brain showed the features of a partially thrombosed giant middle cerebral artery aneurysm, located deep in the left lentiform region and compressing the basal ganglia and the mesencephalon. The angiogram confirmed the aneurysm and its origin from the main trunk of the artery with occlusion of all the branches. A direct approach was unsuitable for the treatment of the aneurysm, so an embolization procedure to occlude the neck of the aneurysm was considered. During the waiting period, the patient improved and became asymptomatic. Follow-up MRI showed complete thrombosis of the aneurysm and eventually, reduction in its size and mass effect. The hemiathetosis may have been the result of direct pressure on the basal ganglia by the aneurysm. The spontaneous intra-aneurysmal thrombosis may have been due to the massive size of the aneurysm and its narrow neck.
一名10岁女孩出现右上肢和下肢逐渐加重的异常运动及无力症状达6周。无颅内压升高的表现。脑部计算机断层扫描和磁共振成像（MRI）显示左豆状核区深处有一个部分血栓形成的大脑中动脉巨大动脉瘤，压迫基底神经节和中脑。血管造影证实了动脉瘤及其起源于动脉主干且所有分支闭塞。直接手术方法不适用于该动脉瘤的治疗，因此考虑采用栓塞术封堵动脉瘤颈部。在等待期间，患者病情好转且无症状。随访MRI显示动脉瘤完全血栓形成，最终动脉瘤大小及占位效应减小。半身舞动症可能是动脉瘤对基底神经节直接压迫的结果。动脉瘤内自发血栓形成可能是由于动脉瘤巨大且颈部狭窄。
