She had mild ptosis and proptosis in her left eye with 3\u2009mm of anisocoria. On examination, she was found to have 60 prism dioptres exotropia with minimal motility limitation (\u22121 adduction, elevation and depression) in the left eye. With a provisional diagnosis of acquired third nerve palsy, she underwent MRI brain and orbit with contrast, which showed enhancing nodular lesion along the course of the left oculomotor nerve in the prepontine cistern which was hyperintense on T1 post-contrast and hypointense on T2\/3D Fast Imaging Employing Steady-state Acquisition-weighted images at interpeduncular cistern suggestive of a schwannoma. This led to the final diagnosis of acquired third nerve palsy in the setting of oculomotor schwannoma. The patient opted for observation in view of the small size, isolated and slowly progressive nature of the tumour.<\/jats:p>","DOI":"10.1136\/bcr-2024-262958","type":"journal-article","created":{"date-parts":[[2024,12,10]],"date-time":"2024-12-10T19:11:12Z","timestamp":1733857872000},"page":"e262958","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Isolated cisternal third cranial nerve schwannoma: an insight into a clinico-radiological features"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-7837-950X","authenticated-orcid":false,"given":"Shrutakirty","family":"Parida","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Kalinga Institute of Medical Sciences, Bhubaneswar, Odisha, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1927-6643","authenticated-orcid":false,"given":"Virender","family":"Sachdeva","sequence":"additional","affiliation":[{"name":"Department of Paediatric Ophthalmology, Strabismus and Neuro-ophthalmology, LV Prasad Eye Institute, Visakhapatnam, Andhra Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4771-1865","authenticated-orcid":false,"given":"Vivekanand Uttamrao","family":"Warkad","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Strabismus and Neuro-ophthalmology, LV Prasad Eye Institute Bhubaneswar Campus, Bhubaneswar, Odisha, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2024,12,10]]},"reference":[{"key":"2025082707022479000_17.12.e262958.1","doi-asserted-by":"crossref","first-page":"1269","DOI":"10.4103\/ajns.AJNS_104_18","article-title":"Sporadic Cisternal Oculomotor Nerve Schwannoma: A Rare Case with Review of Literature","volume":"13","author":"Marutirao","year":"2018","journal-title":"Asian J Neurosurg"},{"key":"2025082707022479000_17.12.e262958.2","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2019-230272","article-title":"Oculomotor schwannoma causing a progressive complete third-nerve palsy","volume":"12","author":"Bentley","year":"2019","journal-title":"BMJ Case Rep"},{"key":"2025082707022479000_17.12.e262958.3","doi-asserted-by":"publisher","DOI":"10.1016\/j.surneu.2006.06.012"},{"key":"2025082707022479000_17.12.e262958.4","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-200203000-00002"},{"key":"2025082707022479000_17.12.e262958.5","doi-asserted-by":"crossref","DOI":"10.25259\/SNI-75-2019","article-title":"Management of oculomotor nerve schwannoma: Systematic review of literature and illustrative case","volume":"10","author":"Muhammad","year":"2019","journal-title":"Surg Neurol Int"},{"key":"2025082707022479000_17.12.e262958.6","doi-asserted-by":"crossref","first-page":"43","DOI":"10.14791\/btrt.2014.2.1.43","article-title":"Oculomotor nerve schwannoma: a case report","volume":"2","author":"Cho","year":"2014","journal-title":"Brain Tumor Res Treat"},{"key":"2025082707022479000_17.12.e262958.7","doi-asserted-by":"crossref","first-page":"149","DOI":"10.3171\/JNS\/2008\/109\/12\/S23","article-title":"Gamma Knife surgery for schwannomas originating from cranial nerves III, IV, and VI","volume":"109 Suppl","author":"Kim","year":"2008","journal-title":"J Neurosurg"},{"key":"2025082707022479000_17.12.e262958.8","doi-asserted-by":"crossref","first-page":"630","DOI":"10.1097\/00006123-199909000-00039","article-title":"Schwannoma of the oculomotor nerve: a case report with consideration of the surgical treatment","volume":"45","author":"Asaoka","year":"1999","journal-title":"Neurosurgery"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2024-262958","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T14:02:35Z","timestamp":1756303355000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2024-262958"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,12]]},"references-count":8,"journal-issue":{"issue":"12","published-online":{"date-parts":[[2024,12,10]]},"published-print":{"date-parts":[[2024,12]]}},"alternative-id":["10.1136\/bcr-2024-262958"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2024-262958","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,12]]}}}
