Liver was coarse in architecture with patchy, mixed echogenic parenchyma. The gallbladder was thickened with excessive coalesced debris. The proximal common bile duct was dilated. Common bile duct 0.4 cm. Echogenic tissue was noted in the region of the common bile duct, which was isoechoic to surrounding fat, measured approximately 1 cm at its widest point. The common bile duct appeared only mildly thickened the last 1 cm prior to the union with the pancreatic duct. The tissue occupation appears to initiate approximately 1 cm cranial to this point. The minor heterogenous changes in the liver could represent metastatic disease if the bile duct occupation is that of tumor versus proliferative inflammatory tissue; both can both resemble each other.
The pancreas was mildly enlarged, dilated duct.
Minor ring-down artifact was noted in the caudal thorax in this patient. Precise caudal thoracic lung radiographs are recommended to assess for potential metastatic disease.
