Authors describe a very unusual case of schwannomas originating in lateral recess of the fourth ventricle. Tumor was completely excised micro-surgically via midline suboccipital craniectomy and C1 laminectomy. Dissection of the surgical specimen revealed that the tumor was completely free from surrounding structures and just hanging in the fourth ventricle. It was not attached to any cranial nerves, brain parenchyma, and blood vessel or to the dura mater. Histopathological examination confirmed the diagnosis of schwannoma. To our knowledge, no such case has been reported so far from this extremely rare location. Relevant literature is reviewed and hypothesis for ectopic location of these tumors has been highlighted.<\/jats:p>","DOI":"10.4103\/1793-5482.103728","type":"journal-article","created":{"date-parts":[[2012,11,22]],"date-time":"2012-11-22T10:38:19Z","timestamp":1353580699000},"page":"151-153","source":"Crossref","is-referenced-by-count":12,"title":["Schwannoma originating in lateral recess of the fourth ventricle"],"prefix":"10.1055","volume":"7","author":[{"given":"Rajneesh","family":"Kachhara","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Bombay Hospital, Indore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prakash","family":"Raje","sequence":"additional","affiliation":[{"name":"Department of Pathology, Bombay Hospital, Indore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Apoorva","family":"Pauranik","sequence":"additional","affiliation":[{"name":"Department of Medicine, MGM Medical College, Indore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2022,9,27]]},"reference":[{"key":"key-10.4103\/1793-5482.103728-1","first-page":"127","volume-title":"Midline cerebellar cystic schwannoma: a case report","author":"Bhatjiwale","year":"1999","journal-title":"Neurol India","ISSN":"https:\/\/id.crossref.org\/issn\/0028-3886","issn-type":"print"},{"key":"key-10.4103\/1793-5482.103728-2","first-page":"357","volume-title":"Cystic schwannoma of the brain stem.Can J Neurol Sci","author":"Ladouceur","year":"1989","journal-title":""},{"key":"key-10.4103\/1793-5482.103728-3","first-page":"454","volume-title":"Solitary olfactory groove schwannoma.J Clin Neurosci","author":"Mirone","year":"2009","journal-title":""},{"key":"key-10.4103\/1793-5482.103728-4","first-page":"777","volume-title":"Fourth ventricular schwannoma.A case report","author":"Redekop","year":"1990","journal-title":"J Neurosurg"},{"key":"key-10.4103\/1793-5482.103728-5","first-page":"147","volume-title":"Intrasellar schwannoma mimicking pituitary adenoma: A case report.J Korean Med Sci","author":"Whee","year":"2002","journal-title":""},{"key":"key-10.4103\/1793-5482.103728-6","doi-asserted-by":"crossref","unstructured":"Riggs H, Clary W.
