Its presentation is non-specific and thus hardly ever preoperatively diagnosed. Its diagnosis often requires surgical corroboration. This case report aims to improve on the preoperative diagnosis with a proposed observed sign on CT. All literature reviewed described radiological findings related to the small bowel; thus, features of small bowel obstruction was the \u201challmark\u201d of internal hernias. This paper intends to describe the features of the sigmoid mesocolon internal hernias, illustrate and propose a never reported configuration of the sigmoid colon. This sigmoid colon configuration has a resemblance to the omega sign. We intend to present a new hallmark sign, which may serve as a clue in the identification of internal hernias involving the sigmoid mesocolon. <\/jats:p>","DOI":"10.1259\/bjrcr.20190127","type":"journal-article","created":{"date-parts":[[2020,1,3]],"date-time":"2020-01-03T17:18:15Z","timestamp":1578071895000},"page":"20190127","source":"Crossref","is-referenced-by-count":2,"title":["The \u201cOmega sign\u201d: a new radiological sign for a rare type of internal hernia involving the sigmoid mesocolon"],"prefix":"10.1093","volume":"6","author":[{"given":"Kino Ceon","family":"Francis","sequence":"first","affiliation":[{"name":"Department of Diagnostic and Interventional Radiology, University Hospital of the West Indies, Mona, Jamaica"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Candice","family":"Daley","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Interventional Radiology, University Hospital of the West Indies, Mona, Jamaica"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bonnie-Paul Regis","family":"Williams","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Interventional Radiology, University Hospital of the West Indies, Mona, Jamaica"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard","family":"Bullock","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Interventional Radiology, University Hospital of the West Indies, Mona, Jamaica"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ulanda","family":"Singh","sequence":"additional","affiliation":[{"name":"Department of Surgery, University Hospital of the West Indies, Mona, Jamaica"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akil","family":"Baker","sequence":"additional","affiliation":[{"name":"Department of Surgery, University Hospital of the West Indies, Mona, Jamaica"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","reference":[{"key":"b1","doi-asserted-by":"publisher","DOI":"10.1007\/s10029-012-1023-1"},{"key":"b2","doi-asserted-by":"publisher","DOI":"10.1007\/s12262-012-0620-7"},{"key":"b3","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-196403000-00008"},{"key":"b4","doi-asserted-by":"publisher","DOI":"10.1148\/rg.2016150113"},{"key":"b5","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v20.i19.5924"},{"key":"b6","first-page":"109","volume":"42","author":"Kayano H","year":"2017","journal-title":"Tokai J Exp Clin Med"},{"key":"b7","doi-asserted-by":"publisher","DOI":"10.1007\/s00595-009-4010-0"},{"key":"b8","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijscr.2011.08.010"},{"key":"b9","doi-asserted-by":"publisher","DOI":"10.1155\/2014\/589649"}],"container-title":["BJR|case reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.birpublications.org\/doi\/pdf\/10.1259\/bjrcr.20190127","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,1,12]],"date-time":"2024-01-12T15:49:43Z","timestamp":1705074583000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/bjrcr\/article\/7244099"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,6]]},"references-count":9,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2020,6]]}},"alternative-id":["10.1259\/bjrcr.20190127"],"URL":"https:\/\/doi.org\/10.1259\/bjrcr.20190127","relation":{},"ISSN":["2055-7159"],"issn-type":[{"value":"2055-7159","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,6]]}}}
