Acute Exacerbation of Chronic Cholecystitis Revealing a Duplicate Gallbladder: A Rare Surgical Challenge

Gallbladder duplication is a rare congenital anomaly that may complicate the diagnosis and surgical management of biliary disease. We report the case of a 42-year-old gentleman presenting with the sudden onset of right upper abdominal pain, nausea, and emesis. Imaging revealed a duplicated gallbladder with cholelithiasis and sonographic features consistent with acute cholecystitis. The patient underwent a laparoscopic cholecystectomy, which revealed a bilobed gallbladder with a single cystic duct. This case highlights the diagnostic and operative challenges associated with gallbladder duplication and emphasizes the importance of preoperative recognition to ensure safe and effective surgical intervention.
