This report discusses a man in his early 30s who developed right-sided SNHL and vertigo 1\u2009week after bilateral parotid swelling and orchitis. Elevated mumps IgM antibody titre confirmed the diagnosis. Audiometry revealed a profound hearing loss in the right ear. MRI showed fluid-attenuated inversion recovery hyperintensities in the right inner ear, indicating labyrinthitis. Despite treatment with oral and intratympanic corticosteroids, hearing did not improve, though vestibular symptoms resolved within a month. This case highlights the pathogenesis of mumps-induced inner ear involvement, aligning with previous studies indicating severe, often irreversible SNHL and transient vestibular symptoms due to viral endolymphatic labyrinthitis. Radiological findings supported the diagnosis, emphasising the importance of comprehensive evaluation in mumps-related complications.<\/jats:p>","DOI":"10.1136\/bcr-2024-262927","type":"journal-article","created":{"date-parts":[[2025,5,2]],"date-time":"2025-05-02T07:46:07Z","timestamp":1746171967000},"page":"e262927","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Exploring the unexpected: sensorineural hearing loss and vertigo as a complication of mumps"],"prefix":"10.1136","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6945-0929","authenticated-orcid":false,"given":"Aswathi","family":"Kallyadan Veetil","sequence":"first","affiliation":[{"name":"Otorhinolaryngology & Head and neck surgery, AIl India Institute Of Medical Sciences - Guwahati, Changsari, Assam, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hanifa","family":"Akthar","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology & Head and neck surgery, All India Institute of Medical Sciences Guwahati, Changsari, Assam, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8095-1230","authenticated-orcid":false,"given":"Ruuzeno","family":"Kuotsu","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology & Head and Neck Surgery, All India Institute of Medical Sciences - Guwahati, Changsari, assam, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5433-1310","authenticated-orcid":false,"given":"Bhupen","family":"Barman","sequence":"additional","affiliation":[{"name":"Internal Medicine, All India Institute of Medical Sciences - Guwahati, Guwahati, Assam, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,5,2]]},"reference":[{"key":"2025082710592024000_18.5.e262927.1","doi-asserted-by":"crossref","first-page":"42","DOI":"10.3949\/ccjm.74.1.42","article-title":"The resurgence of mumps in young adults and adolescents","volume":"74","author":"Shanley","year":"2007","journal-title":"Cleve Clin J Med"},{"key":"2025082710592024000_18.5.e262927.2","doi-asserted-by":"crossref","first-page":"S44","DOI":"10.1080\/00016489.2017.1290826","article-title":"The clinical features and prognosis of mumps-associated hearing loss: a retrospective, multi-institutional investigation in Japan","volume":"137","author":"Morita","year":"2017","journal-title":"Acta Otolaryngol"},{"key":"2025082710592024000_18.5.e262927.3","doi-asserted-by":"crossref","first-page":"337","DOI":"10.1017\/S0022215115000511","article-title":"Vestibular dysfunction in patients with post-mumps sensorineural hearing loss","volume":"129","author":"El-Badry","year":"2015","journal-title":"J Laryngol Otol"},{"key":"2025082710592024000_18.5.e262927.4","doi-asserted-by":"crossref","first-page":"295","DOI":"10.1159\/000276856","article-title":"MRI Evidence of Labyrinthine and Eighth-Nerve Bundle Involvement in Mumps Virus Sudden Deafness and Vertigo","volume":"58","author":"Comacchio","year":"1996","journal-title":"ORL"},{"key":"2025082710592024000_18.5.e262927.5","doi-asserted-by":"crossref","first-page":"329","DOI":"10.1038\/254329a0","article-title":"Experimental viral labyrinthitis","volume":"254","author":"Davis","year":"1975","journal-title":"Nature New Biol"},{"key":"2025082710592024000_18.5.e262927.6","doi-asserted-by":"publisher","DOI":"10.1177\/000348946006900318"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2024-262927","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T17:59:28Z","timestamp":1756317568000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2024-262927"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,5]]},"references-count":6,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2025,5,2]]},"published-print":{"date-parts":[[2025,5]]}},"alternative-id":["10.1136\/bcr-2024-262927"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2024-262927","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,5]]}}}
