Two-thirds of ependymomas arise in the infratentorial or intraventricles, whereas one-third are located supratentorially. But supratentorial "cortical" ependymomas are very rare. We report a case of a cortical ependymoma in a 21-month-old boy. The patient presented with simple partial seizures. This tumor was located in the postcentral gyrus and he had gross total excision. Microscopy and immunohistochemistry showed grade II differentiation ependymoma.
三分之二的室管膜瘤发生于幕下或脑室内,而三分之一位于幕上。但幕上“皮质”室管膜瘤非常罕见。我们报告一例21个月大男孩的皮质室管膜瘤病例。该患者表现为单纯部分性发作。肿瘤位于中央后回,已行肿瘤全切。显微镜检查及免疫组化显示为Ⅱ级分化的室管膜瘤。
