Abstract:
Cholecystohepatic communication is a rare complication of gallbladder rupture in dogs, and its imaging features are not well described. A 10-year-old Pomeranian showed a gallbladder wall defect, a tortuous tubular structure extending into an adjacent ill-defined hepatic lesion. Contrast-enhanced ultrasonography revealed marked enhancement of the tubular structure and weaker heterogeneous enhancement of the hepatic lesion. Laparotomy confirmed gallbladder rupture with severe adhesion at the suspected communication site. Contrast-enhanced ultrasonography enabled delineation of the enhancing tubular structure and improved characterization of the adjacent hepatic inflammation, increasing diagnostic confidence in cholecystohepatic communication secondary to gallbladder rupture.
