Four cases of acute cerebellar infarction producing hydrocephalus are presented. Only the patient, who is submitted to surgical decompression of the posterior fossa, survives, while the other three die. In the latter the necropsy shows a hemorrhagic cerebellar softening in the territory of the inferior posterior cerebellar artery, causing tonsillar herniation and impairment of the liquor drainage at the level of the inferior part of the 4th ventricle. It is suggested that the infarction and the hydrocephalus further progress in "avalanche effect", which is fatal unless prompt surgical decompression can be carried out.
本文报告了4例急性小脑梗死导致脑积水的病例。仅1例接受后颅窝手术减压的患者存活，其他3例死亡。在死亡的3例尸检中显示，小脑后下动脉供血区域出现出血性小脑软化，导致扁桃体疝形成以及第四脑室下部脑脊液引流障碍。提示梗死和脑积水以“雪崩效应”进一步发展，除非能迅速进行手术减压，否则将是致命的。
