Epidermoid tumors located in the fourth ventricle are exceedingly rare. Seven cases of this pathological condition were observed during a 10-year period. Patients were mostly middle-aged men, with a clinical history of relatively short duration (5 months). Clinical symptoms consisted of vertigo and ataxia, followed by incoordination, dysmetria, and tremor at a later stage. Computed tomography scanning represented the main diagnostic technique for these lesions, and typically showed a highly hypodense, round-shaped area within the fourth ventricle, occasionally accompanied by hydrocephaly. Subtotal surgical removal of the cysts produced excellent results in 86% of the cases. The implications of these findings are discussed.
位于第四脑室的表皮样肿瘤极为罕见。在10年期间观察到7例这种病理状况。患者多为中年男性，临床病史相对较短（5个月）。临床症状包括眩晕和共济失调，后期出现不协调、辨距不良和震颤。计算机断层扫描是这些病变的主要诊断技术，通常显示第四脑室内有一个高度低密度的圆形区域，偶尔伴有脑积水。囊肿次全手术切除在86%的病例中取得了良好效果。讨论了这些发现的意义。
