We herein report a rare case of gallbladder torsion with PVG. An 88-year-old woman complained of right hypogastric pain. Ultrasonography (US) showed diffuse wall thickening of her gallbladder and mobile echogenic foci moving inside the portal venous branches. Computed tomography showed a thickened wall of the gallbladder with poor enhancement and tiny pockets of air in the portal venous branches (segments 4 and 5). There was no evidence of other visceral ischemia. She was diagnosed with necrotic cholecystitis and immediately underwent an emergency operation. We found a gangrenous gallbladder with 180\u00b0 clockwise rotation along the longitudinal axis and performed cholecystectomy. We confirmed the disappearance of PVG with US after the operation. Her postoperative course was uneventful. Gallbladder diseases can produce PVG, and US might be a useful diagnostic modality to evaluate changes in PVG.<\/jats:p>","DOI":"10.1093\/jscr\/rjac491","type":"journal-article","created":{"date-parts":[[2022,11,1]],"date-time":"2022-11-01T15:17:53Z","timestamp":1667315873000},"source":"Crossref","is-referenced-by-count":2,"title":["Portal venous gas accompanied by gallbladder torsion: a case report"],"prefix":"10.1093","volume":"2022","author":[{"given":"Takayuki","family":"Tohma","sequence":"first","affiliation":[{"name":"Department of Acute Care Surgery , Chiba Emergency Medical Center, Chiba, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiro","family":"Kobe","sequence":"additional","affiliation":[{"name":"Department of Acute Care Surgery , Chiba Emergency Medical Center, Chiba, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mitsuhiko","family":"Yoshida","sequence":"additional","affiliation":[{"name":"Department of Acute Care Surgery , Chiba Emergency Medical Center, Chiba, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaya","family":"Ushio","sequence":"additional","affiliation":[{"name":"Department of Acute Care Surgery , Chiba Emergency Medical Center, Chiba, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2022,10,31]]},"reference":[{"key":"2022110114270188200_ref1","doi-asserted-by":"crossref","first-page":"1410","DOI":"10.1001\/archsurg.136.12.1410","article-title":"Clinical features and management of hepatic portal venous gas: four case reports and cumulative review of the literature","volume":"136","author":"Kinoshita","year":"2001","journal-title":"Arch Surg"},{"key":"2022110114270188200_ref2","doi-asserted-by":"crossref","first-page":"1628","DOI":"10.3748\/wjg.v26.i14.1628","article-title":"Optimal treatment strategies for hepatic portal venous gas: a retrospective assessment","volume":"26","author":"Gonda","year":"2020","journal-title":"World J Gastroenterol"},{"key":"2022110114270188200_ref3","first-page":"486","article-title":"Gas in the portal veins of the liver in infants;
