BACKGROUND: Choledochal cysts are rare diseases in adults. The risk of malignant transformation is well documented to be age-related and early complete cyst excision is currently advocated. Type IVa cyst management is more controversial. Extensive intrahepatic involvement of the biliary system may preclude complete excision. AIM: The aim of this study was to present a case of type IVa choledochal cyst in a young female patient. CASE REPORT: An 18-year-old female, complaining of right upper quadrant pain, nausea, vomiting, fever, and jaundice was admitted. The diagnosis of type IVa choledochal cyst was made by computerized tomography. The patient was underwent cholecystectomy, excision of the anterior wall of the cyst, and Roux-en-Y hepaticojejunostomy. No postoperative complication was noted and the patient was discharged five days after operation. CONCLUSION: Total cyst excision is the ideal treatment of choledochal cysts in adults. However, in IVa type, due to the extensive intrahepatic involvement of the biliary system, the anatomy of the cyst, and the surgeon's judgment will determine the surgical approach taken for the patient.
