The simultaneous occurrence of all three is exceptionally rare; to date, there have been no reports of them occurring concurrently. This case, however, describes what we believe to be the first documented case of all three conditions presenting simultaneously in a single patient. The management of this rare case involved a combined surgical approach, including open aneurysm repair and partial ectopic nephrectomy.<\/jats:p>","DOI":"10.1136\/bcr-2026-272555","type":"journal-article","created":{"date-parts":[[2026,7,23]],"date-time":"2026-07-23T16:45:23Z","timestamp":1784825123000},"page":"e272555","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Abdominal aortic aneurysm and renal cell carcinoma in the presence of crossed fused renal ectopia"],"prefix":"10.1136","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-8821-5854","authenticated-orcid":false,"given":"Chlo\u00e9","family":"Moran","sequence":"first","affiliation":[{"name":"Manchester Royal Infirmary, Manchester University Foundation Trust, Manchester, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-5546-8773","authenticated-orcid":false,"given":"Zeeshan","family":"Kazmi","sequence":"additional","affiliation":[{"name":"Manchester Royal Infirmary, Manchester University Foundation Trust, Manchester, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen","family":"Ball","sequence":"additional","affiliation":[{"name":"Manchester Royal Infirmary, Manchester University Foundation Trust, Manchester, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2026,7,23]]},"reference":[{"key":"2026072309451323000_19.7.e272555.1","first-page":"11","article-title":"Abdominal aortic aneurysm: A comprehensive review","volume":"16","author":"Aggarwal","year":"2011","journal-title":"Exp Clin Cardiol"},{"key":"2026072309451323000_19.7.e272555.2","first-page":"576","article-title":"The Treatment of Metastatic Renal Cell Carcinoma","volume":"121","author":"Ivanyi","year":"2024","journal-title":"Dtsch Arztebl Int"},{"key":"2026072309451323000_19.7.e272555.3","unstructured":"National Institue for Healthcare and Excellence .
