The history, clinical signs and radiographic and ultrasonographic findings in 16 dogs with pancreatic neoplasia were reviewed retrospectively. Thirteen of the dogs had islet cell carcinoma compatible with insulinoma, one had a pancreatic adenocarcinoma and 2 had secondary invasion of the pancreas, one by a gastric carcinoma and one by an intestinal lymphoma. The clinical signs in the 13 dogs with insulinoma included collapse in 10 dogs, ataxia in 7, weakness in 5, and 2 had seizures. Two of the 16 dogs had jaundice due to biliary obstruction by the primary tumour or metastases. The sensitivities for pancreatic neoplasia were 3 of 16 (19%) for radiography and 12 of 16 (75%) for ultrasonography; the sensitivities for metastasis were 2 of 11 (18%) for radiography and 6 of 11 (55%) for ultrasonography. Biliary obstruction was detected by ultrasonography in both affected dogs.
