MRI demonstrated a cauda equina tumor at L2. Following L1\u20133 laminectomies, intraoperative ultrasound localized the tumor. After dural opening, a vascular tumor was adherent to the cauda equina. Intraoperative nerve stimulation helped to identify the nerve rootlets. Tumor was removed in a piecemeal fashion. Tumor dissection caused periodic spasms in L1\u20133 distributions. A neuromonitoring checklist was used to recover motor evoked potential signals with elevated mean arterial pressures. Hemostasis was challenging with the vascular tumor. Intraoperative ultrasound confirmed tumor debulking. Pathology confirmed metastatic RCC.<\/jats:p>","DOI":"10.3171\/2023.7.focvid2379","type":"journal-article","created":{"date-parts":[[2023,10,1]],"date-time":"2023-10-01T09:22:47Z","timestamp":1696152167000},"page":"V22","source":"Crossref","is-referenced-by-count":1,"title":["Surgical resection of lumbar intradural metastatic renal cell carcinoma"],"prefix":"10.3171","volume":"9","author":[{"given":"Mohamed","family":"Macki","sequence":"first","affiliation":[{"name":"Department of Neurological Surgery, University of California, San Francisco, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vardhaan S.","family":"Ambati","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of California, San Francisco, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christine","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of California, San Francisco, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Tawil","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of California, San Francisco, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abraham","family":"Dada","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of California, San Francisco, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alysha","family":"Jamieson","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of California, San Francisco, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sean","family":"Wilkinson","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of California, San Francisco, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timothy","family":"Chryssikos","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of California, San Francisco, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Praveen V.","family":"Mummaneni","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of California, San Francisco, California"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"5","key":"b1","series-title":"Global Spine J","first-page":"517","article-title":"The challenges of renal cell carcinoma metastatic to the spine: a systematic review of survival and treatment","volume":"8","author":"Goodwin CR","year":"2018","unstructured":"Goodwin CR, Ahmed AK, Boone C,  The challenges of renal cell carcinoma metastatic to the spine: a systematic review of survival and treatment.
