Pial arteriovenous fistulas (pAVF) of the posterior fossa are rare and may present with symptoms secondary to mass effect, venous hypertension or hemorrhage, among others. A case is presented of a previously healthy 2-year-old boy with neurological deficit arising from pAVF of the posteroinferior cerebellar artery. The pAVF was successfully treated with endovascular occlusion.
幕下动静脉瘘（pAVF）较为罕见，可能因占位效应、静脉高压或出血等原因出现症状。本文报道了一例此前健康的 2 岁男孩，因后下小脑动脉的 pAVF 出现神经功能缺损。该 pAVF 经血管内闭塞治疗成功。
