Original publication title: Findings of contrast-enhanced ultrasonography with Sonazoid for cholangiocellular adenoma in three dogs.

Plain-English summary
Three dogs were diagnosed with a rare type of liver tumor called cholangiocellular adenoma, which is usually benign. When veterinarians used a special imaging technique called contrast-enhanced ultrasonography (CEUS) with a contrast agent named Sonazoid, the results looked similar to those of malignant tumors. This can make it tricky to identify the tumor type just by looking at the images. The study highlights the importance of using CEUS to help differentiate between benign and malignant liver lesions in dogs, but it also shows that benign tumors can sometimes appear concerning on imaging tests.

Abstract
Contrast-enhanced ultrasonography (CEUS) is useful to distinguish benign and malignant focal liver lesions in dogs. Cholangiocellular adenoma is an extremely rare benign tumor in dogs and has not been examined using CEUS with Sonazoid. The aim of this study was to describe findings of CEUS with Sonazoid in three dogs with cholangiocellular adenoma. All three dogs showed contrast defects in the Kupffer phase and these findings mimicked malignant neoplasia during the Kupffer phase. Moreover, all dogs showed early washout and hypoechoic lesions relative to the surrounding normal liver parenchyma in the portal phase. To our knowledge, this is the first study to report that CEUS findings of cholangiocellular adenoma with Sonazoid mimicked malignancy in three dogs.
