A 9‐year‐old G iant S chnauzer was referred for polyuria and polydipsia. On abdominal ultrasound, a hyperechoic mass with low color D oppler signal was detected in the medial right hepatic lobe. Contrast‐enhanced ultrasound ( CEUS ) demonstrated increased enhancement of the mass during the arterial phase, and contrast washout during portal and late phases with decreased enhancement relative to the liver. These findings were consistent with primary liver malignancy or liver metastasis. A final diagnosis of cholangiocellular adenoma was made based on histopathology. To our knowledge, this is the first description of a benign hepatic neoplasm exhibiting malignant CEUS characteristics in a dog.
