Intra-pelvic schwannoma is very rare entity that may arise from lumbosacral nerve roots or from sciatic nerve. Radicular pain of the lower limb as a presenting symptom of pelvic schwannoma is extremely rare. In the current report, the patient is presented with a right sided L5 radicular pain typical of lumbar discopathy. Interestingly, a herniated lumbar disc was noted on lumbosacral magnetic resonance imaging (MRI). In pre-operative studies a large pelvic mass was detected in the right pre-sacral area with solid and cystic components consistent with schwannoma. The patient underwent a low midline laparotomy to evacuate the retroperitoneal mass. Uniquely, we found the tumor to be arisen from lumbosacral trunk not from a root or peripheral nerve. Most cases with intra-pelvic schwannoma present so late with vague abdominal and pelvic discomfort or pain, low back pain, urinary and bowel symptoms because of compressive effect of the tumor, or incidentally following gynecologic work-ups; So, these patients are mostly referred to gynecologists and urologists. A neurosurgeon should have a high degree of suspicion to diagnose such an entity among his or her patients presented with pains typical for discopathy.<\/jats:p>","DOI":"10.4103\/1793-5482.144158","type":"journal-article","created":{"date-parts":[[2014,11,7]],"date-time":"2014-11-07T07:09:46Z","timestamp":1415344186000},"page":"51-54","source":"Crossref","is-referenced-by-count":5,"title":["Persistent L5 lumbosacral radiculopathy caused by lumbosacral trunk schwannoma"],"prefix":"10.1055","volume":"12","author":[{"given":"Guive","family":"Sharifi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Loghman Hakim Hospital, Shahid Beheshti University of Medical Sciences, Tehran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amin","family":"Jahanbakhshi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Loghman Hakim Hospital, Shahid Beheshti University of Medical Sciences, Tehran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2022,9,20]]},"reference":[{"key":"key-10.4103\/1793-5482.144158-1","first-page":"34","volume-title":"Spinal neurinomas: Retrospective analysis and long-term outcome of 179 consecutively operated cases and review of the literature","author":"Conti","year":"2004","journal-title":"Surg Neurol"},{"key":"key-10.4103\/1793-5482.144158-2","first-page":"93","volume-title":"Retroperitoneal benign schwannoma: Report of three cases and analysis of clinico-radiologic findings","author":"Dede","year":"2003","journal-title":"Tohoku J Exp Med"},{"key":"key-10.4103\/1793-5482.144158-3","first-page":"293","volume-title":"A large pelvic mass in a 39-year-old man","author":"Gullo","year":"2011","journal-title":"Updates Surg"},{"key":"key-10.4103\/1793-5482.144158-4","first-page":"66","volume-title":"Recurrent retroperitoneal schwannomas displaying different differentiation from primary tumor: Case report and literature review","author":"Li","year":"2010","journal-title":"World J Surg Oncol"},{"key":"key-10.4103\/1793-5482.144158-5","first-page":"108","volume-title":"Chronic sciatica secondary to retroperitoneal pelvic schwannoma","author":"Tong","year":"2003","journal-title":"J Clin Neurosci"},{"key":"key-10.4103\/1793-5482.144158-6","first-page":"55","volume-title":"Robotic-assisted surgical removal of pelvic schwannoma: A novel approach to a rare variant","author":"Konstantinidis","year":"2011","journal-title":"Int J Med Robot"},{"key":"key-10.4103\/1793-5482.144158-7","first-page":"1246","volume-title":"Differential diagnosis of intraspinal and extraspinal non-discogenic sciatica","author":"Kulcu","year":"2008","journal-title":"J Clin Neurosci"},{"key":"key-10.4103\/1793-5482.144158-8","first-page":"99","volume-title":"Resection of a pelvic schwannoma with partial removal of the sacral nerve root","author":"Otsuji","year":"2003","journal-title":"Hepatogastroenterology"},{"key":"key-10.4103\/1793-5482.144158-9","doi-asserted-by":"crossref","unstructured":"Rao M, Sagar P, Duff S, Hulme-Moir M, Brayshaw I.
