The authors describe a rare case of idiopathic distal lenticulostriate artery (LSA) aneurysm in a 5-year-old boy who presented in the emergency department with a sudden onset of headache. Admission computed tomography scans revealed an intracerebral hemorrhage in the left caudate nucleus with intraventricular extension. Angiographic studies demonstrated a left medial LSA aneurysm. The patient underwent a left parasagittal frontal craniotomy, the lateral ventricle was accessed via the anterior transcallosal approach, and the aneurysm was removed after sectioning of the parent vessel. The child left the hospital after 5 days; at that time he was asymptomatic and without motor impairment. The optimum treatment of aneurysms involving small perforating arteries is controversial and depends mainly on the causative factors. The pathogenesis and treatment of these unusual aneurysms are discussed.
作者描述了一例罕见的特发性远端豆纹动脉（LSA）动脉瘤病例，患者为一名5岁男孩，因突发头痛就诊于急诊科。入院时的计算机断层扫描显示左侧尾状核脑出血并破入脑室。血管造影研究显示左侧内侧LSA动脉瘤。患者接受了左侧矢状窦旁额部开颅手术，通过经胼胝体前入路进入侧脑室，在切断供血血管后切除动脉瘤。患儿术后5天出院；当时他无症状且无运动障碍。涉及小穿支动脉的动脉瘤的最佳治疗方法存在争议，主要取决于病因。本文讨论了这些不寻常动脉瘤的发病机制和治疗方法。
