我们介绍了一名 48 岁女性的病例,她出现持续性大腿疼痛,并发现圆锥尾部有一个异质肿块,最符合粘液乳头状室管膜瘤。我们进行了 L2-3 椎板切除术以切除肿瘤。在这个过程中,我们使用了术中超声和神经监测。该视频说明了粘液乳头型室管膜瘤的大体病理学、马尾与肿瘤的有效圆周钝性和锐性分离,以及终丝的识别、准备和切片。该病例还强调了当运动神经根被包裹在肿瘤中时切除大的粘液乳头状室管膜瘤的挑战。在这种情况下,我们必须从腹侧进入肿瘤被膜,以解剖穿过肿瘤的马尾神经。患者同意参与我们的研究
We present the case of a 48-yr-old female who presented with persistent thigh pain and was found to have a heterogeneous mass caudal to the conus most consistent with a myxopapillary ependymoma. We performed L2-3 laminectomies for tumor resection. For this procedure, we used intraoperative ultrasound as well as neuromonitoring. This video illustrates the gross pathology of a myxopapillary ependymoma, effective circumferential blunt and sharp dissection of the cauda equina from the tumor, and identification, preparation, and sectioning of the filum terminale. This case also underlines the challenges of removing a large myxopapillary ependymoma when motor nerve rootlets are encapsulated in the tumor. In this case, we were obligated to enter the tumor capsule ventrally in order to dissect away cauda equina nerves passing through the tumor. The patient consented to be part of our research study
