A miniature dachshund, 5 years and 3 months of age, with a history of cholecystitis associated with biliary calculus that had developed one year previously, presented with anorexia and vomiting. A series of examinations, including CT imaging by drip infusion cholangiography (DIC-CT), revealed that no bile was flowing into the gallbladder. Thickening of the gallbladder wall and a biliary calculus occupying the lumen of the gallbladder with a laminated internal structure were also found. Based on the results of a detailed examination,the gallbladder was extracted. E.coli and Enterococcus sp. were isolated by microbiological tests inside the gallbladder and around its outer wall. The findings of drug susceptibility tests indicated that the E. coli could be a substrate-specific, broad spectrum, βhlactamase-producing bacterium. In this case, administration of faropenem sodium was initiated before the surgery and the postoperative course was good. DIC-CT imaging can properly visualize the biliary duct system, and an explanation that relied on these images was useful for the dog's owner. It was thought that surgical treatment should actively be considered to prevent a relapse of cholecystitis in cases involving cholecystitis associated with biliary calculi.
