The authors present a case of meningeal melanocytoma arising from Meckel's cave. A coal-black, vascular tumor was partially removed by surgery. Histopathologically, the tumor lacked anaplastic features. Immunohistochemical studies confirmed that the tumor was of neuroectodermal origin and had low proliferating activity. The patient underwent gamma knife radiosurgery for the residual tumor, in which 25 Gy of radiation was delivered to the tumor margin. Three years after irradiation, the tumor showed marked shrinkage without complication.
作者报告了一例起源于梅克尔腔的脑膜黑素细胞瘤病例。通过手术部分切除了一个煤黑色的血管性肿瘤。组织病理学检查显示，该肿瘤缺乏间变特征。免疫组织化学研究证实，该肿瘤起源于神经外胚层，增殖活性较低。患者对残留肿瘤进行了伽玛刀放射外科治疗，肿瘤边缘接受了25 Gy的辐射。放疗三年后，肿瘤明显缩小，无并发症。
