Insulinomas are functional insulin‐secreting tumours of the beta cells of the pancreatic islets which are rare in cats. Clinical signs are a result of hypoglycaemia and include seizures, collapse, weakness, ataxia, disorientation, mental dullness and visual disturbances. An 11‐year‐old male neutered domestic shorthair cat was presented with a history of having a single abnormal neurological episode. Persistent hypoglycaemia, hyperinsulinaemia and the presence of a well‐defined pancreatic nodule on abdominal ultrasound resulted in a suspected diagnosis of insulinoma. Multiphasic CT angiography revealed a well‐defined, homogeneous pancreatic mass which was isoattenuating to pancreatic parenchyma on precontrast images, had marked contrast enhancement in the arterial phase and moderate enhancement in the venous phase. CT angiography was a useful imaging modality for evaluating this case of histologically confirmed malignant insulinoma and its associated metastases.
