1. Abstract
Cauda equina Neuroendocrine Tumor (NET), previous known as cauda equina paragangliomas, is uncommon neoplasm in adults. In this study, we retrospectively reviewed two cases of cauda equina NET patients who had underwent surgical treatment in our department. We reviewed patient age, gender, presenting symptom, tumor radiological feature, surgical procedure, pathologic data and postoperative complications. Two cases were all clinically non-functional cauda equina NETs without sympathetic symptom. While image-based differential diagnosis of cauda equina tumors is still difficult and definite diagnosis depends on pathology and immunohistochemical staining, resecting the tumor with minimally invasive technique has good curative effect.
