The aim of this multicenter, retrospective case series study was to describe the CT findings in dogs with surgically confirmed colonic torsion. Medical records were searched for dogs with surgically confirmed colonic torsion following abdominal CT. Five dogs met the inclusion criteria. Three had a history of chronic intermittent diarrhea prior to presentation. Two dogs presented with acute vomiting, diarrhea, and abdominal pain and one dog presented with acute vomiting and lethargy. Computed tomographic findings in all dogs with surgically confirmed colonic torsion include: \u201cwhirl sign,\u201d displacement and distension of the cecum and colon, focal narrowing of the colon, and distension of the mesenteric vasculature in all dogs (5\/5); streaky peritoneal fat and peritoneal effusion (4\/5), pneumatosis coli (2\/5), small intestinal distension (2\/5), portal vein thrombosis (1\/5), and reduced colonic wall contrast enhancement (1\/5). In all dogs (5\/5), the torsion site was the descending colon and demonstrated an anticlockwise rotation. At surgery, three of the five dogs had a partial colonic torsion with hyperemia at the site of obstruction and two of the five dogs had a complete torsion with marked necrosis of the colonic wall. Displacement of the colon and cecum, segmental distension and focal narrowing of the colon, the presence of a \u201cwhirl sign\u201d and distension of the mesenteric vasculature are CT findings highly suggestive of colonic torsion.<\/jats:p>","DOI":"10.1111\/vru.12830","type":"journal-article","created":{"date-parts":[[2019,12,14]],"date-time":"2019-12-14T11:10:27Z","timestamp":1576321827000},"page":"190-196","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["CT findings in five dogs with surgically confirmed colonic torsion"],"prefix":"10.1111","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7070-341X","authenticated-orcid":false,"given":"Pablo","family":"Barge","sequence":"first","affiliation":[{"name":"Diagnostic Imaging Department Pride Veterinary Centre  Derby UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caroline J.","family":"Fina","sequence":"additional","affiliation":[{"name":"Diagnostic Imaging Department Pride Veterinary Centre  Derby UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeremy R.","family":"Mortier","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Imaging, VetCT Consultants in Telemedicine St Johns Innovation Centre  Cambridge UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3166-1461","authenticated-orcid":false,"given":"Ian D.","family":"Jones","sequence":"additional","affiliation":[{"name":"Diagnostic Imaging Department Pride Veterinary Centre  Derby UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,12,14]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-950X.1984.tb00767.x"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/vru.12595"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748-5827.2006.00018.x"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.2460\/javma.2005.227.253"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.2460\/javma.237.8.907"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.5326\/JAAHA-MS-5829"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/jsap.12694"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2001.tb00931.x"},{"key":"e_1_2_8_10_1","first-page":"1096","article-title":"Ileocecocolic volvulus in a German shepherd dog","volume":"55","author":"Javard R","year":"2014","journal-title":"Can Vet J"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/vru.12053"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.3389\/fvets.2016.00033"},{"key":"e_1_2_8_13_1","first-page":"133","volume-title":"BSAVA Manual of Canine and Feline Abdominal Imaging","author":"O'Brien R","year":"2009"},{"key":"e_1_2_8_14_1","first-page":"322","volume-title":"Miller's Anatomy of the Dog","author":"Evans HE","year":"2013"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/vru.12467"},{"key":"e_1_2_8_16_1","first-page":"894","volume-title":"Veterinary Diagnostic Radiology","author":"Thrall DE","year":"2018"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2261011392"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748-5827.1998.tb03698.x"},{"key":"e_1_2_8_19_1","first-page":"1","article-title":"Radiographic and CT features of colonic entrapment due to an omental rent in a dog","author":"Brand KJ","year":"2019","journal-title":"Vet Radiol Ultrasound"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/vru.12079"},{"key":"e_1_2_8_21_1","doi-asserted-by":"publisher","DOI":"10.1111\/vsu.12674"},{"key":"e_1_2_8_22_1","doi-asserted-by":"publisher","DOI":"10.1080\/00480169.2004.36389"},{"key":"e_1_2_8_23_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.tcam.2014.09.002"},{"key":"e_1_2_8_24_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.tcam.2014.09.007"},{"key":"e_1_2_8_25_1","first-page":"E1","article-title":"Septic peritonitis: etiology, pathophysiology, and diagnosis","volume":"33","author":"Ragetly GR","year":"2011","journal-title":"Compend Contin Educ Vet"},{"key":"e_1_2_8_26_1","doi-asserted-by":"publisher","DOI":"10.1136\/inpract.31.2.66"},{"key":"e_1_2_8_27_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2263011540"},{"key":"e_1_2_8_28_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2004.04034.x"},{"key":"e_1_2_8_29_1","doi-asserted-by":"publisher","DOI":"10.1111\/vru.12691"},{"key":"e_1_2_8_30_1","doi-asserted-by":"publisher","DOI":"10.1259\/bjr\/35714052"}],"container-title":["Veterinary Radiology &amp;
