On arrival he was in adrenal crisis. Biochemistry revealed anterior hypopituitarism with low cortisol, thyroxine, testosterone and a slightly raised prolactin. He was commenced on steroids, thyroxine and testosterone. MRI pituitary gland was reported to have a 9.4\u2009mm microadenoma. Cabergoline was started for a possible microprolactinoma. Follow-up MRI showed increase in the size of complex cystic lesion causing chiasmal compression raising a possibility of craniopharyngioma. Visual fields assessment was normal. In view of the rapid enlargement, to protect vision and obtain a tissue diagnosis he underwent endoscopic trans-sphenoidal surgery. A cystic lesion was noted intraoperatively originating from pituitary stalk with intrasellar and suprasellar extension. It was filled with white caseous material and fluid. Histology revealed epidermoid cyst. His headache resolved postoperatively.<\/jats:p>","DOI":"10.1136\/bcr-2020-241065","type":"journal-article","created":{"date-parts":[[2021,3,24]],"date-time":"2021-03-24T12:49:13Z","timestamp":1616590153000},"page":"e241065","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Pituitary infundibular epidermoid cyst: a rare cause of hypopituitarism"],"prefix":"10.1136","volume":"14","author":[{"given":"Sajjad","family":"Ahmad","sequence":"first","affiliation":[{"name":"Department of Diabetes and Endocrinology, University Hospital of Wales, Cardiff, Cardiff, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashutosh","family":"Surya","sequence":"additional","affiliation":[{"name":"Department of Diabetes and Endocrinology, University Hospital of Wales, Cardiff, Cardiff, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caroline","family":"Hayhurst","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, University Hospital of Wales, Cardiff, Cardiff, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen","family":"Davies","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, University of Wales College of Medicine, Cardiff, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2021,3,24]]},"reference":[{"key":"2025082801201540000_14.3.e241065.1","doi-asserted-by":"crossref","first-page":"359","DOI":"10.4103\/0028-3886.53266","article-title":"Intracranial epidermoid cyst: magnetic resonance imaging features","volume":"57","author":"Kumari","year":"2009","journal-title":"Neurol India"},{"key":"2025082801201540000_14.3.e241065.2","doi-asserted-by":"publisher","DOI":"10.3171\/2009.4.PEDS08489"},{"key":"2025082801201540000_14.3.e241065.3","doi-asserted-by":"publisher","DOI":"10.1227\/00006123-198904000-00014"},{"key":"2025082801201540000_14.3.e241065.4","doi-asserted-by":"crossref","first-page":"275","DOI":"10.2176\/nmc.43.275","article-title":"Surgical treatment of intracranial epidermoid tumors","volume":"43","author":"Akar","year":"2003","journal-title":"Neurol Med Chir"},{"key":"2025082801201540000_14.3.e241065.5","doi-asserted-by":"crossref","first-page":"108","DOI":"10.1097\/WNQ.0b013e318266c267","article-title":"Epidermoid cyst of the pituitary stalk:case report and review of the literature","volume":"23","author":"Costa","year":"2013","journal-title":"Neurosurg Q"},{"key":"2025082801201540000_14.3.e241065.6","doi-asserted-by":"crossref","first-page":"437","DOI":"10.3171\/2016.11.JNS161605","article-title":"Complete endoscopic resection of a pituitary stalk epidermoid cyst using a combined infrasellar interpituitary and suprasellar endonasal approach: case report","volume":"128","author":"Nakassa","year":"2018","journal-title":"J Neurosurg"},{"key":"2025082801201540000_14.3.e241065.7","article-title":"Suprasellar epidermoid cyst originating from the infundibulum: case report and literature review","volume":"10","author":"McCormack","year":"2018","journal-title":"Cureus"},{"key":"2025082801201540000_14.3.e241065.8","doi-asserted-by":"crossref","first-page":"110","DOI":"10.1016\/j.wneu.2019.06.205","article-title":"Infundibular epidermoid cyst: case report and systematic review","volume":"130","author":"Khan","year":"2019","journal-title":"World Neurosurg"},{"key":"2025082801201540000_14.3.e241065.9","doi-asserted-by":"crossref","first-page":"26","DOI":"10.1016\/j.wneu.2020.09.030","article-title":"Resection of an isolated pituitary stalk epidermoid cyst through a Pretemporal approach: case report and review of the literature","volume":"146","author":"Lee","year":"2021","journal-title":"World Neurosurg"},{"key":"2025082801201540000_14.3.e241065.10","doi-asserted-by":"crossref","unstructured":"Miller J , Hdeib A , Cohen A .
