Choledochal cyst presenting with neonatal intestinal obstruction: A case report

Background: Most patients with choledochal cysts are diagnosed during childhood. Therefore, the aim of this study is to report a case of early detected choledochal cyst in a neonate patient presenting with intestinal obstruction.   Case Presentation: A 5-day-old baby girl was brought to the hospital with a chief complaint of bilious vomiting. No history of jaundice was found. Ultrasound in the third trimester (37 weeks) showed an anechoic cyst with a smooth wall, no septum, with a size of 5.5x4.7x4.7 cm, suspected ovarian cyst. At 4 days old, MRCP showed dilated right and left Intrahepatic bile duct with a normal gallbladder, suspected as choledochal cyst Todani type 1. The patient was operated on at 7 days old and was discharged 15 days after surgery. Nine months after discharge, the patient was in good condition with no complaints of jaundice nor acholic stool and normal liver function test. Conclusion: Prenatal diagnosis of choledochal cyst gave awareness to receive appropriate treatment. Bowel obstruction without jaundice could be an early symptom of a choledochal cyst in neonates.
