Its occurrence within the intracranial cavity is extremely rare, accounting for only 0.1 to 0.2% of all intracranial tumors. Even more exceptional is its presence in the sellar\/parasellar region, with only five cases previously reported in the literature. This report describes the sixth known case of a sellar OC in a 30-year-old female who presented with progressive visual loss and bitemporal hemianopia. Radiological investigations revealed a calcified mass in the sellar-suprasellar region, initially suspected to be a calcified pituitary adenoma or chordoma. The patient underwent endoscopic transsphenoidal resection, and histopathological analysis confirmed the diagnosis of OC based on classic features including a hyaline cartilage cap, underlying bone with endochondral ossification, and absence of mitotic activity or nuclear atypia. Postoperatively, the patient showed significant visual improvement and was treated with adjuvant radiotherapy due to the tumor's central location. This case highlights the importance of considering OC in the differential diagnosis of calcified sellar masses and underscores the value of a multidisciplinary approach\u2014including imaging, surgical resection, and histopathological evaluation\u2014in establishing an accurate diagnosis and guiding effective management.<\/jats:p>","DOI":"10.1055\/s-0046-1822672","type":"journal-article","created":{"date-parts":[[2026,5,6]],"date-time":"2026-05-06T22:43:37Z","timestamp":1778107417000},"page":"887-891","source":"Crossref","is-referenced-by-count":0,"title":["Osteochondroma of the Sella Turcica: A Rare Mimic in the Spectrum of Sellar Masses"],"prefix":"10.1055","volume":"21","author":[{"given":"Sunila","family":"Jain","sequence":"additional","affiliation":[{"name":"Department of Histopathology, Sir Gangaram Hospital, New Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0660-9939","authenticated-orcid":false,"given":"Md Ali","family":"Osama","sequence":"additional","affiliation":[{"name":"Department of Pathology, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anshul","family":"Gupta","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Sir Gangaram Hospital, New Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satnam Singh","family":"Chhabra","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Sir Gangaram Hospital, New Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2026,5,6]]},"reference":[{"key":"ref1","first-page":"147","article-title":"An osteological study on the prevalence of osteochondromas","volume":"37","author":"G R Gaumer","year":"2017","journal-title":"Iowa Orthop J"},{"issue":"03","key":"ref2","doi-asserted-by":"crossref","first-page":"37","DOI":"10.17116\/patol201577337-40","article-title":"[Osteochondroma in children and adolescents]","volume":"77","author":"D V Rogozhin","year":"2015","journal-title":"Arkh Patol"},{"issue":"04","key":"ref3","doi-asserted-by":"crossref","first-page":"380","DOI":"10.1080\/02688699844952","article-title":"Dural osteochondroma: case report, review of the literature and proposal of a new classification","volume":"12","author":"G F Haddad","year":"1998","journal-title":"Br J Neurosurg"},{"issue":"10","key":"ref4","first-page":"1079","article-title":"[A case of intracranial osteochondroma (author's transl)]","volume":"5","author":"H Himuro","year":"1977","journal-title":"No Shinkei Geka"},{"issue":"11","key":"ref5","first-page":"1063","article-title":"[A case of intracranial osteochondroma: its MR images]","volume":"17","author":"T Hatayama","year":"1989","journal-title":"No Shinkei Geka"},{"issue":"01","key":"ref6","doi-asserted-by":"crossref","first-page":"37","DOI":"10.2176\/nmc.49.37","article-title":"Osteochondroma of the sella turcica presenting with intratumoral hemorrhage","volume":"49","author":"T Inoue","year":"2009","journal-title":"Neurol Med Chir (Tokyo)"},{"issue":"04","key":"ref7","doi-asserted-by":"crossref","first-page":"380","DOI":"10.1055\/s-0036-1596056","article-title":"Osteochondroma presenting as a calcified mass in the sellar region and review of the literature","volume":"78","author":"K Sekiguchi","year":"2017","journal-title":"J Neurol Surg A Cent Eur Neurosurg"},{"issue":"04","key":"ref8","doi-asserted-by":"crossref","first-page":"2352","DOI":"10.1097\/MS9.0000000000001855","article-title":"Intracranial osteochondroma arising from the posterior clinoid process: a rare case report with diagnostic challenges and comprehensive literature review","volume":"86","author":"B R Thapa","year":"2024","journal-title":"Ann Med Surg (Lond)"}],"container-title":["Asian Journal of Neurosurgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0046-1822672.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,9]],"date-time":"2026-10-09T22:57:34Z","timestamp":1791586654000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0046-1822672"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,5,6]]},"references-count":8,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2026,10,9]]},"published-print":{"date-parts":[[2026,12]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0046-1822672","archive":["Portico","CLOCKSS"],"relation":{},"ISSN":["1793-5482","2248-9614"],"issn-type":[{"value":"1793-5482","type":"print"},{"value":"2248-9614","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,5,6]]}}}
