The authors report a juvenile pilocytic astrocytoma (JPA) in the trigone of an 11-year-old girl, apparently with disseminated lesions that disappeared spontaneously after the removal of primary lesion. Gadolinium-enhanced magnetic resonance images (MRIs) showed features suggestive of the development of multicentric spread of the tumor at the initial diagnosis. Histologically the primary tumor showed the typical features of a JPA. Serial postoperative MRIs demonstrated that everything except a remnant of the primary tumor seemed to regress spontaneously without any adjuvant therapy. The site of origin of this tumor is thought to be the subependymal glia of the occipital lobe.
作者报告了一例11岁女孩三角区的青少年毛细胞型星形细胞瘤（JPA），显然存在播散性病变，在切除原发病变后这些病变自行消失。钆增强磁共振成像（MRI）显示在初始诊断时提示肿瘤多中心播散发展的特征。组织学上，原发肿瘤显示出JPA的典型特征。术后系列MRI表明，除原发肿瘤残余部分外，所有病变似乎在未进行任何辅助治疗的情况下自行消退。该肿瘤的起源部位被认为是枕叶的室管膜下胶质细胞。
