Autopsy was performed on a 52-year-old man with a 20-year history of neurological symptoms. At autopsy, both a brain stem tumor and a spinal cord tumor were found. These showed the features of pilocytic astrocytoma histologically. A pilocytic astrocytoma was also found in the optic chiasm upon microscopical examination. These three tumors were thought to be multicentric astrocytomas, because there was no continuity among them and no evidence of dissemination or metastasis by any pathway. From a review of the literature, the present case is considered to be an exceedingly rare one because of the multicentric sites of occurrence.
对一名有20年神经症状病史的52岁男性进行了尸检。尸检时，发现脑干肿瘤和脊髓肿瘤。组织学检查显示这些肿瘤具有毛细胞型星形细胞瘤的特征。显微镜检查发现视交叉处也有毛细胞型星形细胞瘤。这三个肿瘤被认为是多中心星形细胞瘤，因为它们之间没有连续性，也没有任何途径的播散或转移证据。从文献回顾来看，由于肿瘤发生部位多中心，本病例被认为极为罕见。
