Abstract:
This case report describes an extremely rare association between gallbladder agenesis and choledochal cyst (CC). A 9-year-old girl presented with recurrent abdominal pain in the right upper quadrant. Radiological studies revealed a CC type IVa and an agenesis of gallbladder and cystic duct. Due to the possibility of biliary neoplasm, the patient underwent cyst resection and hepaticoduodenostomy. Histopathological findings showed inflamed fibrous tissue covered by biliary epithelium with no evidence of malignancy.
