A 13-month-old intact female Akita was referred to a specialty hospital with suspected pancreatitis. Radiographs at the time of presentation showed atypical positioning of the pylorus and proximal descending duodenum, spleen and right kidney. Abdominal ultrasound showed features suggestive of a diaphragmatic rent with pyloric entrapment, resulting in pyloric and extrahepatic biliary obstruction. Subsequent exploratory coeliotomy identified a right dorsolateral diaphragmatic rent with pyloric, proximal duodenal, right pancreatic and associated omental entrapment. A diaphragmatic herniorraphy was performed resulting in complete clinical resolution.
