Major findings

  • Non-obstructive, circumferential mural mass involving the descending duodenum with mucosal irregularity
  • Wide gastroduodenal angle
  • Reduced serosal detail in the right cranial abdomen
  • Wispy soft tissue in the retroperitoneal space

Minor findings

  • Barium reflux into the esophagus on the 30 minute study
  • Corrugated jejunum
  • Mural duodenal mass may be non-infectious inflammatory (ulcer, duodenitis) from external causes (pancreatitis, pancreatic neoplasia), infectious inflammatory (fungal) or neoplastic (adenocarcinoma)
  • Right cranial quadrant peritonitis from pancreatitis, pancreatic mass or inflammation from bowel mass
  • Ultrasound to look for pancreatic involvement and perform aspirates of the mass and/or fluid
  • Thoracic radiographs to assess for metastatic disease
  • All candidates identified an abnormality of the duodenum. Many candidates failed to recognize that the lesion was mural and diagnosed a foreign body. Several candidates did not recognize that the right cranial quadrant was abnormal outside the duodenum and/or did not identify regional peritonitis. Unsuccessful candidates identified multiple lesions in the bowel leading to a diagnosis of infiltrative disease throughout the jejunum. Several candidates listed neoplasia as their only differential despite the signalment and history of the dog.
