We describe a 35-year-old man with a history of remote closed head injury who presented with new neurologic deficits. A noncontrast head CT scan showed hyperattenuation involving both temporal lobes, frontal lobes, basal meninges, and cerebellum. A subsequent contrast-enhanced MR examination of the brain showed enhancement in the basal cisterns extending into the upper cervical spine and throughout the spinal canal. Gross, histologic, and immunohistochemical analysis revealed meningeal melanocytoma.
我们描述了一名35岁男性，有既往闭合性颅脑损伤史，现出现新的神经功能缺损。头颅非增强CT扫描显示双侧颞叶、额叶、基底脑膜和小脑呈高密度影。随后的脑部增强磁共振检查显示基底池强化，延伸至上颈椎并贯穿椎管。大体、组织学和免疫组化分析显示为脑膜黑素细胞瘤。
