Chronic abdominal pain leads to discovery of congenital anomaly.

A 43-year-old female with no history of a cholecystectomy presented with chronic right sided abdominal pain that became worse after fatty food intake. This led to an extensive workup for gallbladder disease for the patient's source of her pain. She had an initial ultrasound, which showed a collapsed gallbladder around gallstones, which signified chronic cholecystitis. This was confirmed with a hepatobiliary iminodiacetic acid scan with Choletec and morphine as there was no visualization of the gallbladder. Due to the patient's persistent abdominal pain with associated symptoms and radiographic evidence of cholecystitis, she was taken to the operating theater for a laparoscopic cholecystectomy and the absence of a gallbladder was discovered. The goal of this clinical case report is to highlight this rare anomaly and how it presents in a clinical setting.
