His dysphagia was initially thought to be related to the atypical diagnosis of achalasia and was being considered for an elective laparoscopic Heller myotomy. On performing CT of the abdomen, a large renal mass was discovered. However, predicament remained regarding the exact aetiology of this renal mass. This case highlights a tremendously intriguing case of dysphagia with an underlying aetiology that has not been reported elsewhere previously.<\/jats:p>","DOI":"10.1136\/bcr-2018-227610","type":"journal-article","created":{"date-parts":[[2019,8,26]],"date-time":"2019-08-26T13:54:01Z","timestamp":1566827641000},"page":"e227610","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Unusual cause of dysphagia"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4990-5172","authenticated-orcid":false,"given":"Dion","family":"Koh","sequence":"first","affiliation":[{"name":"Upper Gastrointestinal Surgery, Monash Health, Clayton, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Udit","family":"Thakur","sequence":"additional","affiliation":[{"name":"Upper Gastrointestinal Surgery, Monash Health, Clayton, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei Mou","family":"Lim","sequence":"additional","affiliation":[{"name":"Upper Gastrointestinal Surgery, Monash Health, Clayton, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,8,26]]},"reference":[{"key":"2025082701430680000_12.8.e227610.1","doi-asserted-by":"crossref","first-page":"449","DOI":"10.5009\/gnl14446","article-title":"The Pathogenesis and Management of Achalasia: Current Status and Future Directions","volume":"9","author":"Ates","year":"2015","journal-title":"Gut Liver"},{"key":"2025082701430680000_12.8.e227610.2","doi-asserted-by":"publisher","DOI":"10.1038\/ajg.2013.196"},{"key":"2025082701430680000_12.8.e227610.3","first-page":"411","article-title":"An Overview of Achalasia and Its Subtypes","volume":"13","author":"Patel","year":"2017","journal-title":"Gastroenterol Hepatol"},{"key":"2025082701430680000_12.8.e227610.4","first-page":"1","article-title":"Pseudoachalasia: a diagnostic challenge","volume":"28","author":"Roushan","year":"2014","journal-title":"Med J Islam Repub Iran"},{"key":"2025082701430680000_12.8.e227610.5","doi-asserted-by":"crossref","first-page":"139","DOI":"10.18295\/2075-0528.2655","article-title":"Laparoscopic deroofing of large renal simple cysts causing gastric symptoms","volume":"7","author":"Mathew","year":"2007","journal-title":"Sultan Qaboos Univ Med J"},{"key":"2025082701430680000_12.8.e227610.6","doi-asserted-by":"crossref","first-page":"337","DOI":"10.5152\/tud.2017.78379","article-title":"Giant hydronephrosis: still a reality!","volume":"43","author":"Kaura","year":"2017","journal-title":"Turk J Urol"},{"key":"2025082701430680000_12.8.e227610.7","doi-asserted-by":"crossref","first-page":"19","DOI":"10.3892\/mco.2016.876","article-title":"Giant hydronephrosis due to ureteropelvic junction obstruction: A rare case report, and a review of the literature","volume":"5","author":"Wang","year":"2016","journal-title":"Mol Clin Oncol"},{"key":"2025082701430680000_12.8.e227610.8","first-page":"1","article-title":"About a Case Report of Giant Hydronephrosis","volume":"2013","author":"Mediavilla","year":"2013","journal-title":"Case Rep Urol"},{"key":"2025082701430680000_12.8.e227610.9","doi-asserted-by":"publisher","DOI":"10.1136\/pgmj.71.837.409"},{"key":"2025082701430680000_12.8.e227610.10","doi-asserted-by":"crossref","first-page":"101","DOI":"10.1007\/s00455-011-9346-0","article-title":"Endoscopic findings in patients presenting with dysphagia: analysis of a national endoscopy database","volume":"27","author":"Krishnamurthy","year":"2012","journal-title":"Dysphagia"},{"key":"2025082701430680000_12.8.e227610.11","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.326.7386.433"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2018-227610","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T08:43:13Z","timestamp":1756284193000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2018-227610"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,8]]},"references-count":11,"journal-issue":{"issue":"8","published-online":{"date-parts":[[2019,8,26]]},"published-print":{"date-parts":[[2019,8]]}},"alternative-id":["10.1136\/bcr-2018-227610"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2018-227610","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2019,8]]}}}
