Abstract

A 23-year-old woman presented with ipsilateral hemiparesia due to rupture of a left occipital arteriovenous malformation (AVM). Emergency decompression (the onset-operation interval was 46 minutes,) was carried out and the patient could leave the hospital upon recovery without neurological deficits. In general, Kernohan's phenomenon is caused by the gradual displacement of the cerebral peduncle against the tentorial edge caused by compression by the contralateral mass. This phenomenon is very rare among the cases with spontaneous intracranial hemorrhage and only three cases including the present one have been reported in the literature. In all cases the onset-operation intervals of were very short. Kernohan's phenomenon associated with a ruptured AVM is a rare condition and emergency decompression is required.

摘要

一名23岁女性因左枕叶动静脉畸形（AVM）破裂出现同侧偏瘫。进行了紧急减压（发病至手术间隔为46分钟），患者康复后可出院，无神经功能缺损。一般来说，克诺汉现象是由对侧肿块压迫导致大脑脚逐渐向小脑幕边缘移位引起的。这种现象在自发性颅内出血病例中非常罕见，文献中仅报道了包括本例在内的3例。所有病例的发病至手术间隔都非常短。与破裂AVM相关的克诺汉现象是一种罕见情况，需要紧急减压。
