A 46-year-old woman was referred to our hospital because of back pain and an abnormality on chest imaging. Chest computed tomography showed a well-delineated tumor in the left paravertebral space. Histological analysis of the resected tumor revealed perivascular pseudorosettes, and immunoreactivity for glial fibrillary acidic protein established the diagnosis of ependymoma. A few cases have been reported in the ovary, broad ligament, sacrococcygeal region, lungs, and mediastinum, but the pathogenesis has not yet been clarified. Female predominance in these tumors and organogenesis of the sites may suggest a key to the pathogenesis.
一名46岁女性因背痛和胸部影像学异常被转诊至我院。胸部计算机断层扫描显示左椎旁间隙有一个边界清晰的肿瘤。对切除肿瘤的组织学分析显示有血管周围假菊形团，胶质纤维酸性蛋白免疫反应阳性确诊为室管膜瘤。卵巢、阔韧带、骶尾部、肺和纵隔均有少数病例报道，但发病机制尚未阐明。这些肿瘤中女性占优势以及发病部位的器官发生可能提示了发病机制的关键所在。
