Presented entity was incidentally found in head CT scan of 12-year-old male. Based on the radiological characteristics in CT scans and MR images, the diagnosis of intradiploic arachnoid cyst (AC) was suggested. After surgical intervention and histopathological analysis of the specimen, the diagnosis was confirmed. We assume this is the first description of large intrasphenoid AC without any traumatic or iatrogenic cause. The literature provides many different terms for the phenomenon. We are proposing the term\n                    <jats:italic>intradiploic arachnoid diverticulum<\/jats:italic>\n                    as the more accurate for capturing the essence of the phenomenon. It provides clear differentiation of the entities from classical arachnoid cysts since they are of different anatomical localization (intradural vs. extradural) and etiopathogenesis. Management with arachnoid diverticulum is not yet established, but observation with serial imaging studies should be recommended as primary management in case of asymptomatic cyst. When cyst is symptomatic, surgical treatment may be required.\n                  <\/jats:p>","DOI":"10.1007\/s00381-023-06255-x","type":"journal-article","created":{"date-parts":[[2023,12,21]],"date-time":"2023-12-21T10:02:48Z","timestamp":1703152968000},"page":"1271-1276","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Large intradiploic arachnoid cyst of the skull in child\u2014a case report and new terminology proposition"],"prefix":"10.1007","volume":"40","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5321-7743","authenticated-orcid":false,"given":"Adrian","family":"Dro\u017cd\u017c","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3639-4422","authenticated-orcid":false,"given":"Tomasz","family":"Wojciechowski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0740-5049","authenticated-orcid":false,"given":"Bogdan","family":"Ciszek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5227-727X","authenticated-orcid":false,"given":"Zygmunt","family":"Stopa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2023,12,21]]},"reference":[{"key":"6255_CR1","doi-asserted-by":"publisher","unstructured":"Kumar Lahiri A, Chilvers G (2018) Nontraumatic intradiploic arachnoid cyst of the sphenoid bone.
