A 29-year-old man had two episodes of seizures in 9 months. Following the first seizure he developed hemiparesis, which gradually progressed. Investigations revealed a large cerebral convexity mass lesion simulating a meningioma. During operation, a reddish-brown and well-defined tumor located in the subarachnoid space was encountered. Histopathological examination revealed a typical ependymoma. Extra-axial cerebral convexity ependymomas are extremely rare. The case is reported and a brief review of six similar cases reported in the literature is undertaken.
一名29岁男性在9个月内发作了两次癫痫。首次癫痫发作后，他出现了偏瘫，且逐渐加重。检查发现一个大脑凸面的巨大肿块病变，形似脑膜瘤。手术中，在蛛网膜下腔发现了一个红棕色、边界清晰的肿瘤。组织病理学检查显示为典型的室管膜瘤。轴外大脑凸面室管膜瘤极为罕见。现报告该病例，并对文献中报道的6例类似病例进行简要回顾。
