Co-existence of Double Gallbladder and Choledochal Cyst in a Single Patient.

Additional anatomical structures are rare but can be mistaken for other conditions, causing misdiagnoses and poor outcomes for patients. The presence of concurrent anomalies within the extra structures further complicates a rare situation. We present a case of a patient with two gallbladders and a choledochal cyst diagnosed via radiography and confirmed by exploratory laparotomy. He underwent a cholecystectomy, choledochal cyst resection, and hepaticojejunostomy, and he was doing well as of his last follow-up. This case highlights the need to consider radiological imaging in patients with choledochal cysts carefully.
