The clinical and imaging features of a paraganglioma of the cauda equina are presented. A peridural anesthesia revealed the cauda equina compression syndrome in a 68 years old man who presented first with a urinary retention. Total surgical excision of a long round-shaped encapsulated tumor was uneventful. Macroscopically this lesion filled up the spinal canal and resembled to a meningioma. It was firmly attached to the filum terminale. Adjacent large arterialized vessels visible on MRI were spared. Although the diagnosis could be evoked pre-operatively on some suggestive patterns on the MRI, the pathological findings finally confirmed the diagnosis of paraganglioma. Along with the evidence of specific light microscopic features, the use of an immunocytochemical demonstration of synaptophysine in these tumors allows a confident diagnosis to be made.
本文介绍了一例马尾神经节细胞瘤的临床及影像学特征。一名68岁男性患者最初表现为尿潴留，硬膜外麻醉显示存在马尾神经受压综合征。对一个长圆形包膜肿瘤进行了完整的手术切除，过程顺利。宏观上，该病变充满椎管，类似脑膜瘤。它与终丝紧密相连。MRI上可见的相邻大的动脉化血管未受影响。尽管术前根据MRI上的一些提示性表现可推测诊断，但最终病理结果确诊为神经节细胞瘤。除了具有特定的光镜特征外，在这些肿瘤中使用突触素免疫细胞化学染色可做出可靠的诊断。
