There was an incidental finding of increased mastoid signalling in 5.8 per cent (<jats:italic>n<\/jats:italic>= 29), of which 20.7 per cent (6 of 29) were reported as bilateral cases. The diagnosis of \u2018mastoiditis\u2019 was found in 39.7 per cent (29 of 73). None of these patients had any pathology identified clinically. Other significant pathology was identified in a further 8.8 per cent (<jats:italic>n<\/jats:italic>= 44).<\/jats:p><\/jats:sec><jats:sec id=\"S0022215118001949_sec_a4\" sec-type=\"conclusion\"><jats:title>Conclusion<\/jats:title><jats:p>The diagnosis of mastoiditis is primarily clinical. An incidental finding of high signalling in the mastoid region on magnetic resonance imaging is highly unlikely to represent actual clinical disease. In patients who are scanned for other reasons and who do not complain of otological symptoms, such findings are unlikely to require otolaryngology input.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s0022215118001949","type":"journal-article","created":{"date-parts":[[2018,11,5]],"date-time":"2018-11-05T04:13:15Z","timestamp":1541391195000},"page":"1010-1012","source":"Crossref","is-referenced-by-count":5,"title":["Incidental mastoiditis on magnetic resonance imaging scans: clinical relevance and cost implications"],"prefix":"10.1017","volume":"132","author":[{"given":"Y","family":"Abbas","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H S","family":"Yuen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Trinidade","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G","family":"Watters","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2018,11,5]]},"reference":[{"key":"S0022215118001949_ref5","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-011-1506-1"},{"key":"S0022215118001949_ref1","doi-asserted-by":"publisher","DOI":"10.1542\/pir.30-6-233"},{"key":"S0022215118001949_ref2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.155.2.3983389"},{"key":"S0022215118001949_ref9","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-015-4113-5"},{"key":"S0022215118001949_ref6","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199201023260107"},{"key":"S0022215118001949_ref3","doi-asserted-by":"crossref","first-page":"514","DOI":"10.1177\/014556130808700909","article-title":"Mastoiditis on MRI: fact or artifact?","volume":"87","author":"Meredith","year":"2008","journal-title":"Ear Nose Throat J"},{"key":"S0022215118001949_ref7","doi-asserted-by":"publisher","DOI":"10.1007\/s00247-016-3545-7"},{"key":"S0022215118001949_ref8","doi-asserted-by":"crossref","first-page":"629","DOI":"10.1055\/s-0032-1312861","article-title":"Incidental findings in paranasal sinuses and mastoid cells: a cross-sectional magnetic resonance imaging (MRI) study in a pediatric radiology department","volume":"184","author":"Von Kalle","year":"2012","journal-title":"Rofo"},{"key":"S0022215118001949_ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.crad.2012.07.019"}],"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\/S0022215118001949","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,10,31]],"date-time":"2019-10-31T13:38:10Z","timestamp":1572529090000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0022215118001949\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,11]]},"references-count":9,"journal-issue":{"issue":"11","published-print":{"date-parts":[[2018,11]]}},"alternative-id":["S0022215118001949"],"URL":"https:\/\/doi.org\/10.1017\/s0022215118001949","relation":{},"ISSN":["0022-2151","1748-5460"],"issn-type":[{"value":"0022-2151","type":"print"},{"value":"1748-5460","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,11]]}}}
