Plain-English summary
A 9-year-old Giant Schnauzer was brought to the vet for increased thirst and urination. An abdominal ultrasound revealed a mass in the liver that looked suspicious for cancer. However, further testing with a special ultrasound technique showed that the mass was actually a benign tumor called a cholangiocellular adenoma, which can sometimes appear like a malignant tumor. The dog received treatment based on this diagnosis, and the outcome was positive, as the benign nature of the tumor was confirmed through a biopsy.

Abstract
A 9-year-old Giant Schnauzer was referred for polyuria and polydipsia. On abdominal ultrasound, a hyperechoic mass with low color Doppler 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.
