In patients with chronic back pain and systemic symptoms, this case emphasizes the value of early imaging and a high level of clinical suspicion for AAA. AEF and rupture are two major consequences of a delayed diagnosis. Improving results in such complicated vascular presentations requires prompt management and careful postoperative surveillance. The case highlights the importance of early imaging and clinical suspicion for AAA, as delayed diagnosis can lead to complications like AEF and rupture.<\/jats:p>","DOI":"10.1002\/ccr3.71912","type":"journal-article","created":{"date-parts":[[2026,1,20]],"date-time":"2026-01-20T12:34:36Z","timestamp":1768912476000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Delayed Diagnosis of a Giant Abdominal Aortic Aneurysm Complicating to Aortoenteric Fistula: A Case Report and Literature Review"],"prefix":"10.1002","volume":"14","author":[{"given":"Ola Gamal Badawi","family":"Khalil","sequence":"first","affiliation":[{"name":"Kassala Teaching Hospital  Kassala Sudan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammed Eltaieb Ali","family":"Mohammed","sequence":"additional","affiliation":[{"name":"Kassala Teaching Hospital  Kassala Sudan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Salah Eldin Mohamed Elmustafa","family":"Hassan","sequence":"additional","affiliation":[{"name":"Wad Madani Cardiac Centre  Wad Madani Sudan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Khalid Alshibli Dafalla","family":"Gasmalla","sequence":"additional","affiliation":[{"name":"Sudan Medical Specialization Board  Khartoum Sudan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rania Ahmed Elsiddig","family":"Hassan","sequence":"additional","affiliation":[{"name":"Internal Medicine Department Gezira University  Wad Madani Sudan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5882-0090","authenticated-orcid":false,"given":"Yousif Omer Elgaili","family":"Yousif","sequence":"additional","affiliation":[{"name":"Alzaim Alazhari University  Khartoum Sudan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,1,20]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2018.09.020"},{"issue":"1","key":"e_1_2_11_3_1","doi-asserted-by":"crossref","first-page":"S108","DOI":"10.21037\/cdt.2017.09.13","article-title":"Abdominal Aortic Aneurysm Screening: Concepts and Controversies","volume":"8","author":"Zucker E.
