It can occur in cases of chronic otitis media squamous type (unsafe type) due to dehiscence of the sigmoid sinus plate caused by cholesteatoma. The presentation of which is that of pulsatile tinnitus. However, we present an unusual case of sigmoid sinus diverticulum occurring concurrently with chronic otitis media mucosal type (safe type) but in the absence of pulsatile tinnitus. This case report highlights the diagnostic challenges and management of this rare clinical scenario.<\/jats:p>","DOI":"10.1136\/bcr-2023-259052","type":"journal-article","created":{"date-parts":[[2024,7,3]],"date-time":"2024-07-03T14:45:26Z","timestamp":1720017926000},"page":"e259052","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Sigmoid sinus diverticulum without pulsatile tinnitus occurring concurrently with chronic otitis media mucosal type"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8095-1230","authenticated-orcid":false,"given":"Ruuzeno","family":"Kuotsu","sequence":"first","affiliation":[{"name":"ENT and Head and Neck Surgery, All India Institute of Medical Sciences\u2014Kalyani, Kalyani, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ajay","family":"Mallick","sequence":"additional","affiliation":[{"name":"ENT and Head and Neck Surgery, All India Institute of Medical Sciences\u2014Kalyani, Kalyani, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manaswita","family":"Roy","sequence":"additional","affiliation":[{"name":"ENT and Head and Neck Surgery, All India Institute of Medical Sciences\u2014Kalyani, Kalyani, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arundhati","family":"Mukherjee","sequence":"additional","affiliation":[{"name":"ENT and Head and Neck Surgery, All India Institute of Medical Sciences\u2014Kalyani, Kalyani, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2024,7,3]]},"reference":[{"key":"2025082711053640000_17.7.e259052.1","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A6602"},{"key":"2025082711053640000_17.7.e259052.2","doi-asserted-by":"publisher","DOI":"10.1177\/019459989310900512"},{"key":"2025082711053640000_17.7.e259052.3","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0b013e3182a4756c"},{"key":"2025082711053640000_17.7.e259052.4","doi-asserted-by":"publisher","DOI":"10.1177\/0284185113481698"},{"key":"2025082711053640000_17.7.e259052.5","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0b013e31822a1c7d"},{"key":"2025082711053640000_17.7.e259052.6","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0b013e31822e5b8d"},{"key":"2025082711053640000_17.7.e259052.7","doi-asserted-by":"crossref","first-page":"262","DOI":"10.1007\/s12070-017-1177-3","article-title":"Doing Mastoidectomy along with Tympanic membrane repair reduces the need for revision procedures: A prospective study","volume":"70","author":"Garg","year":"2018","journal-title":"Indian J Otolaryngol Head Neck Surg"},{"key":"2025082711053640000_17.7.e259052.8","doi-asserted-by":"publisher","DOI":"10.1067\/mhn.2000.104640"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2023-259052","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T18:05:42Z","timestamp":1756317942000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2023-259052"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,7]]},"references-count":8,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2024,7,3]]},"published-print":{"date-parts":[[2024,7]]}},"alternative-id":["10.1136\/bcr-2023-259052"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2023-259052","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,7]]}}}
