Incidental Gallbladder Duplication Detected on Imaging in an Adult With Nonspecific Gastrointestinal Symptoms: A Case Report

Gallbladder duplication is a rare congenital biliary anomaly that can present significant diagnostic and surgical challenges if unrecognized. We present the case of a 29-year-old male with nonspecific gastrointestinal symptoms in whom a gallbladder duplication was initially identified on ultrasound and further evaluated using computed tomography (CT), without evidence of inflammation or biliary obstruction. The anomaly was considered incidental and unrelated to the presenting symptoms, and no surgical intervention was required. Accurate preoperative identification of this variant is vital to prevent iatrogenic complications should the patient require a cholecystectomy in the future.
