The aim of this study was to describe the imaging characteristics of pylorogastric (PG), duodenogastric (DG), and true\u2010gastrogastric (true\u2010GG) intussusceptions. In this multicenter retrospective study, available medical records and imaging (radiographs, ultrasound [US], and computed tomography [CT]) were evaluated. Group allocation (PG, DG, and true\u2010GG) was based on US\/CT findings, or surgical\/necropsy findings if only radiographs were available. Available surgical\/necropsy follow\u2010up was reported. Twenty\u2010five dogs and one cat (7 weeks\u201310 years) were included, representing 22 males, four females, and multiple breeds. Twenty\u2010two presented with vomiting. They were diagnosed via US (\n                    <jats:italic>n<\/jats:italic>\n                    \u00a0=\u00a021), CT (\n                    <jats:italic>n<\/jats:italic>\n                    \u00a0=\u00a02), or surgery (\n                    <jats:italic>n<\/jats:italic>\n                    \u00a0=\u00a03). There were 14 PG, 9 true\u2010GG, and 3 DG intussusceptions. A rounded soft tissue opaque mass in the pylorus was present in 8\/9 PG and 1\/1 DG cases with radiographs. Moderate to marked wall thickening was present in all true\u2010GG and most PG cases on US\/CT, predominantly affecting the submucosal layer. Surgical\/necropsy follow\u2010up was available in 17 cases diagnosed via imaging and showed spontaneous resolution of five true\u2010GG and one PG intussusception. Two cases classified as PG based on imaging were described as DG at surgery\/necropsy. There are some overlapping features of PG and DG intussusceptions on radiographs and US. Moderate to marked submucosal thickening seen with PG and true\u2010GG cases likely represents edema\/congestion. Spontaneous resolution of true\u2010GG and PG intussusceptions is possible. US and CT were diagnostic of the type of intussusception in most cases.\n                  <\/jats:p>","DOI":"10.1111\/vru.70213","type":"journal-article","created":{"date-parts":[[2026,7,30]],"date-time":"2026-07-30T09:06:15Z","timestamp":1785402375000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Imaging Characteristics of Pylorogastric, Duodenogastric, and True\u2010Gastrogastric Intussusception in 25 Dogs and One Cat"],"prefix":"10.1111","volume":"67","author":[{"given":"Dylan","family":"Burton","sequence":"first","affiliation":[{"name":"Department of Clinical Sciences, College of Veterinary Medicine and Biomedical Sciences Colorado State University  Fort Collins Colorado USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4128-8269","authenticated-orcid":false,"given":"Linda","family":"Dillenbeck","sequence":"additional","affiliation":[{"name":"Department of Environmental and Radiological Health Sciences College of Veterinary Medicine and Biomedical Sciences Colorado State University  Fort Collins Colorado USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6578-6521","authenticated-orcid":false,"given":"Megan","family":"Stadler","sequence":"additional","affiliation":[{"name":"Colorado State University Veterinary Teaching Hospital Colorado State University  Fort Collins Colorado USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9147-6079","authenticated-orcid":false,"given":"Wilfried","family":"Mai","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences and Advanced Medicine School of Veterinary Medicine University of Pennsylvania  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anthony","family":"Fischetti","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Imaging Schwarzman Animal Medical Center  New York City New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8169-3061","authenticated-orcid":false,"given":"Christine","family":"Gremillion","sequence":"additional","affiliation":[{"name":"Department of Large Animal Clinical Sciences College of Veterinary Medicine &amp; Biomedical Sciences Texas A&amp;M University  College Station Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4385-1000","authenticated-orcid":false,"given":"Pablo","family":"Espinosa\u2010Mur","sequence":"additional","affiliation":[{"name":"Vets Choice Radiology LLC  Northbrook Illinois USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaime","family":"Rechy","sequence":"additional","affiliation":[{"name":"VEG ER for Pets  White Plains New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandra","family":"Gibalski","sequence":"additional","affiliation":[{"name":"VCA Alameda East Veterinary Hospital  Denver Colorado USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kelsey","family":"Cline","sequence":"additional","affiliation":[{"name":"VCA Advanced Veterinary Care Center  Fishers Indiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,30]]},"reference":[{"key":"e_1_2_10_2_1","first-page":"523","article-title":"Intussusception in Dogs and Cats","volume":"9","author":"Lewis D.
