Gallbladder duplication is a rare anatomical variation with an incidence of approximately 1 in 3800 to 4000 live births, resulting from aberrant biliary organogenesis. This case report discusses a 35-year-old female who presented with intermittent lower abdominal pain, with initial imaging revealing a complex left adnexal cyst. Follow-up CT and ultrasound examinations revealed 2 distinct gallbladder-like structures in the gallbladder fossa, each with a cystic duct draining into the common bile duct. This finding is indicative of true gallbladder duplication (H-shaped type) and was noted incidentally. The patient was asymptomatic regarding the duplication, and the management included gynecological follow up for the ovarian cysts while monitoring the gallbladder. This case underscores the need for awareness of gallbladder duplication in imaging, as it may lack symptoms but could lead to complications during surgery. Awareness of this anomaly can guide future management and surgical interventions, ensuring patient safety and optimal outcomes.
