Objectives To assess the prevalence of rare visceral aneurysms on CAT scans performed for diagnosis and follow-up of patients with other vascular pathologies.  Methods This cross-sectional study began by accessing all reports from CAT scans performed between January 2005 and July 2021 at a private hospital of excellence located in the city of S\u00e3o Paulo. A software program for pre-indexed reports was used to search the Radiological Information System (RIS) database to identify reports of patients with intra-abdominal aneurysms.  Results CAT scan reports from 92,883 patients were accessed. Of these, 2,597 (2.795%) showed intra-abdominal aneurysms, 937 (1.063%) of which were visceral, including 158 (0.171%) rare visceral aneurysms, which were more frequent among male patients and in the following segments: celiac trunk (0.098%), superior mesenteric (0.033%), left gastric (0.010%), pancreatic-duodenal (0.009%), and gastroduodenal arteries (0.005%) and the pancreatic arch (0.004%). Lower prevalence was found in other segments. Additional findings revealed concomitance of rare visceral aneurysms with other intra-abdominal aneurysms ranging from 11.11% to 66.67%.  Conclusions The prevalence of rare visceral aneurysms in a large population undergoing CAT scan was 0.171%, with greater involvement in male patients.<\/jats:p>","DOI":"10.1590\/1677-5449.202300742","type":"journal-article","created":{"date-parts":[[2023,10,13]],"date-time":"2023-10-13T11:37:05Z","timestamp":1697197025000},"source":"Crossref","is-referenced-by-count":2,"title":["Prevalence of rare visceral aneurysms on 92,833 CAT scans (2005-2021)"],"prefix":"10.1590","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1458-5276","authenticated-orcid":false,"given":"Sergio Quilici","family":"Belczak","sequence":"first","affiliation":[{"name":"Instituto de Aprimoramento e Pesquisa em Angiorradiologia e Cirurgia Endovascular,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1903-7738","authenticated-orcid":false,"given":"Nathalia Almeida Cardoso da","family":"Silva","sequence":"additional","affiliation":[{"name":"Instituto Angiomar,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3824-4740","authenticated-orcid":false,"given":"Matheus Toledo","family":"Nora","sequence":"additional","affiliation":[{"name":"Instituto de Aprimoramento e Pesquisa em Angiorradiologia e Cirurgia Endovascular,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6409-8762","authenticated-orcid":false,"given":"Paula Ribeiro do Prado","family":"Chadud","sequence":"additional","affiliation":[{"name":"Instituto de Aprimoramento e Pesquisa em Angiorradiologia e Cirurgia Endovascular,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0389-6634","authenticated-orcid":false,"given":"Luciana Helena","family":"Benetti","sequence":"additional","affiliation":[{"name":"Instituto de Aprimoramento e Pesquisa em Angiorradiologia e Cirurgia Endovascular,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0218-2496","authenticated-orcid":false,"given":"Camila de Freitas","family":"Corr\u00eaa","sequence":"additional","affiliation":[{"name":"Instituto de Aprimoramento e Pesquisa em Angiorradiologia e Cirurgia Endovascular,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2282-2892","authenticated-orcid":false,"given":"Adriano","family":"Tchibana","sequence":"additional","affiliation":[{"name":"Hospital Israelita Albert Einstein,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8833-2402","authenticated-orcid":false,"given":"Ricardo","family":"Aun","sequence":"additional","affiliation":[{"name":"Instituto de Aprimoramento e Pesquisa em Angiorradiologia e Cirurgia Endovascular,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2023]]},"reference":[{"issue":"6","key":"ref1","first-page":"1442","article-title":"Contemporary","volume":"61","author":"Shukla AJ","year":"2015","journal-title":"J Vasc Surg"},{"issue":"4","key":"ref2","doi-asserted-by":"crossref","first-page":"514","DOI":"10.1016\/j.jvir.2015.12.024","article-title":"E B, Li D-C, Xu J.
