Cauda Equina Neuroendocrine Tumors (CE-NET), previously referred to as paragangliomas are a rare subset of spinal tumors, with limited data on imaging. Herein, we present a retrospective review of clinical and imaging findings of CE-NETs in ten patients who were evaluated at our institution over the past two decades. All patients had well-defined intradural lesions in the lumbar spine which demonstrated slow growth. A review of imaging findings revealed the presence of an eccentric vascular pedicle along the dorsal aspect of the tumor in 8 of the 10 patients (eccentric vessel sign), a distinctive finding that has not previously been reported with this tumor and may help improve the accuracy of imaging-based diagnosis. In all cases, a gross-total resection was performed, with resolution of symptoms in most of the cases.
马尾神经内分泌肿瘤（CE-NET），以前被称为副神经节瘤，是一种罕见的脊髓肿瘤亚型，其影像学数据有限。在此，我们回顾性分析了过去 20 年来在我院就诊的 10 例 CE-NET 患者的临床和影像学表现。所有患者的腰椎均有边界清楚的硬脊膜内病变，生长缓慢。影像学表现回顾显示，10 例患者中有 8 例（偏心血管征）肿瘤背侧存在偏心性血管蒂，这是一个以前未曾报道过的特征性表现，可能有助于提高基于影像学的诊断准确性。所有患者均行大体全切除，大多数患者症状缓解。
