Magnetic resonance imaging demonstrated both solid and cystic components in the tumor. The cystic component appeared slightly hyperintense compared to cerebrospinal fluid on fluid-attenuated inversion recovery (FLAIR) imaging. A hypointense tubular structure was identified in the cystic component on 3D driven equilibrium sequencing. These imaging findings are unusual for cystic meningioma. However, awareness of these unusual imaging features is important to determine appropriate treatment strategies although cystic meningioma at the CPA is extremely rare.<\/jats:p>","DOI":"10.1177\/19714009221096831","type":"journal-article","created":{"date-parts":[[2022,5,3]],"date-time":"2022-05-03T09:57:08Z","timestamp":1651571828000},"page":"777-779","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Unusual imaging characteristics of cystic meningioma in cerebellopontine angle"],"prefix":"10.1177","volume":"35","author":[{"given":"Saki","family":"Adachi","sequence":"first","affiliation":[{"name":"Department of Radiology, Clinical Research Institute, National Hospital Organization Kyushu Medical Center, Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7417-739X","authenticated-orcid":false,"given":"Koji","family":"Yamashita","sequence":"additional","affiliation":[{"name":"Department of Radiology, Clinical Research Institute, National Hospital Organization Kyushu Medical Center, Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akira","family":"Nakamizo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Clinical Research Institute, National Hospital Organization Kyushu Medical Center, Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshiyuki","family":"Amano","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Clinical Research Institute, National Hospital Organization Kyushu Medical Center, Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seiya","family":"Momosaki","sequence":"additional","affiliation":[{"name":"Department of Pathology, Clinical Research Institute, National Hospital Organization Kyushu Medical Center, Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomoyuki","family":"Noguchi","sequence":"additional","affiliation":[{"name":"Department of Radiology, Clinical Research Institute, National Hospital Organization Kyushu Medical Center, Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2022,5,3]]},"reference":[{"issue":"3","key":"bibr1-19714009221096831","first-page":"129","volume":"47","author":"Gerganov V","year":"2003","journal-title":"J Neurosurg Sci"},{"key":"bibr2-19714009221096831","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-007-0679-x"},{"key":"bibr3-19714009221096831","doi-asserted-by":"publisher","DOI":"10.3171\/2013.10.FOCUS13367"},{"key":"bibr4-19714009221096831","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.13.5.8210595"},{"key":"bibr5-19714009221096831","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000013179"},{"key":"bibr6-19714009221096831","doi-asserted-by":"publisher","DOI":"10.1007\/s00701-016-2898-x"},{"key":"bibr7-19714009221096831","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejrad.2003.10.019"},{"key":"bibr8-19714009221096831","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.42.6.529"},{"key":"bibr9-19714009221096831","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.11.6.1749851"},{"key":"bibr10-19714009221096831","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.35.12.1720"},{"issue":"6","key":"bibr11-19714009221096831","first-page":"1211","volume":"27","author":"Preece MT","year":"2006","journal-title":"AJNR Am J Neuroradiol"}],"container-title":["The Neuroradiology Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/19714009221096831","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/19714009221096831","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/19714009221096831","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T22:37:02Z","timestamp":1777588622000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/19714009221096831"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,5,3]]},"references-count":11,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2022,12]]}},"alternative-id":["10.1177\/19714009221096831"],"URL":"https:\/\/doi.org\/10.1177\/19714009221096831","relation":{},"ISSN":["1971-4009","2385-1996"],"issn-type":[{"value":"1971-4009","type":"print"},{"value":"2385-1996","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,5,3]]}}}
