Computed tomography showed a tegmental defect (approximately 2\u00a0\u00d7\u00a02\u00a0cm) at the right mastoid antrum. A T1-weighted, gadolinium-enhanced magnetic resonance imaging scan showed pneumocephalus in both lateral ventricles, which was directly connected to the mastoid cavity via a brain abscess and a bone defect in the skull base. Radical mastoidectomy was performed to remove the cholesteatoma. The roof of the mastoid cavity was covered extensively with fascia and a pedicled temporalis muscle flap. One week post-operatively, computed tomography and magnetic resonance imaging showed no pneumocephalus.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215112002848_sec3\"><jats:title>Conclusion:<\/jats:title><jats:p>Pneumocephalus arising from a cholesteatoma-induced brain abscess and extending into the lateral ventricles is an important entity, with an atypical appearance on computed tomography and magnetic resonance imaging.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s0022215112002848","type":"journal-article","created":{"date-parts":[[2012,12,7]],"date-time":"2012-12-07T05:09:19Z","timestamp":1354856959000},"page":"192-195","source":"Crossref","is-referenced-by-count":0,"title":["Extensive pneumocephalus extending into the lateral ventricles from a brain abscess: an intracranial complication of cholesteatoma"],"prefix":"10.1017","volume":"127","author":[{"given":"Y","family":"Tamura","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"Suzuki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"Yamamoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T","family":"Yoshida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2012,12,7]]},"reference":[{"key":"S0022215112002848_ref7","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215100061910"},{"key":"S0022215112002848_ref5","doi-asserted-by":"publisher","DOI":"10.1016\/0090-3019(81)90231-7"},{"key":"S0022215112002848_ref2","first-page":"104","article-title":"Intracranial complications of suppurative otitis media: 13 years' experience","volume":"16","author":"Kangsanarak","year":"1995","journal-title":"Am J Otol"},{"key":"S0022215112002848_ref4","doi-asserted-by":"publisher","DOI":"10.1007\/BF01642114"},{"key":"S0022215112002848_ref1","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198605000-00010"},{"key":"S0022215112002848_ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjoto.2008.10.001"},{"key":"S0022215112002848_ref6","doi-asserted-by":"publisher","DOI":"10.1055\/s-2002-33464-1"}],"container-title":["The Journal of Laryngology &amp; Otology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0022215112002848","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,4,24]],"date-time":"2019-04-24T15:52:27Z","timestamp":1556121147000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0022215112002848\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,12,7]]},"references-count":7,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2013,2]]}},"alternative-id":["S0022215112002848"],"URL":"https:\/\/doi.org\/10.1017\/s0022215112002848","relation":{},"ISSN":["0022-2151","1748-5460"],"issn-type":[{"value":"0022-2151","type":"print"},{"value":"1748-5460","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,12,7]]}}}
