Signalment:5-year-old intact male rabbit
History:This animal had an approximately two month history of persistent, gaseous, gastric distension with normal stools. Survey and contrast radiographs suggested an intestinal obstruction. An exploratory laparotomy was performed, and a mass was identified in the area of the duodenal-jejunal intersection, with adhesion of the colon to the serosal surface.
Gross Lesions:At necropsy, there was abdominal effusion. The omental fat was adhered to the previous surgical site, which did not have gross evidence of stricture or perforation. The left hepatic lobe contained a large cystic mass and there was a small firm nodule in the proximal duodenum.
