Multiseptated Gallbladder in a Three-Month-Old Puppy: A Case Report

Multiseptated gallbladder (MSG), also know as “honeycomb gallbladder,” is a rare biliary anomaly well documented in human medicine but infrequently reported in dogs. This report describes the imaging features of MSG in a three-month-old, intact female German Shepherd Dog. The patient was clinically asymptomatic, and hematological and biochemical findings were within normal limits. Abdominal ultrasonography demonstrated multiple curvilinear echogenic septa within the gallbladder lumen, producing a characteristic honeycomb-like pattern. Further evaluation with contrast-enhanced computed tomography (CT) confirmed numerous septal structures extending from the gallbladder wall into the lumen. In addition, small hyperattenuating foci consistent with choleliths were detected. Considering the patient’s young age and the absence of clinical and laboratory abnormalities, the findings were interpreted as most consistent with a congenital anatomical variation. This case emphasizes the importance of recognizing rare congenital gallbladder anomalies in young dogs and highlights the complementary value of advanced imaging techniques, particularly USG and CT, in the detailed assessment of atypical hepatobiliary conditions.
