A 50-year-old female complained of back pain. Computed tomography showed a well-defined spindle-shaped mass 3.4 x 1.0 cm in size in the left paravertebral posterior mediastinum at the Th 3-4 level. The tumor was completely resected via thoracoscopic surgery, which showed no invasion into the surrounding tissue. It consisted of a cyst with a tiny mural solid element. By means of histological and immunohistochemical examinations, we diagnosed the tumor as ependymoma, and the patient remains alive 59 months after resection. As far as we know, 8 reported cases with primary mediastinal ependymoma have been reported. They had the following specific characteristics: (1) All patients were adult females; (2) The tumors were usually located at the paravertebral upper mediastinum; (3) Most of the tumors consisted of cystic and solid elements; (4) The tumors usually made no invasion into the surrounding tissues, though 2 cases had lymph-node metastases.
一名50岁女性主诉背痛。计算机断层扫描显示，在胸3-4水平的左椎旁后纵隔有一个边界清晰的纺锤形肿块，大小为3.4×1.0厘米。通过胸腔镜手术将肿瘤完全切除，显示未侵犯周围组织。它由一个带有微小壁内实性成分的囊肿组成。通过组织学和免疫组化检查，我们将该肿瘤诊断为室管膜瘤，患者在切除术后59个月仍存活。据我们所知，已报道8例原发性纵隔室管膜瘤病例。它们具有以下特定特征：（1）所有患者均为成年女性；（2）肿瘤通常位于椎旁上纵隔；（3）大多数肿瘤由囊性和实性成分组成；（4）肿瘤通常不侵犯周围组织，不过有2例发生了淋巴结转移。
