ABSTRACT

The choledocal cyst is a defect of the biliary extrahepatic route, the incidence is 1 in 100-150,000 newborns. This paper reports the case of a female newborn with choledocal cyst detected prenatally, from a 32-year-old mother, 2nd term pregnancy, who was diagnosed in the routine obstetric ultrasound as an abdominal fetal cyst. An anatomic obstetric ultrasound confirmed the diagnosis that was defined of a probable hepatic origin. Newborn was delivered at 39 weeks by caesarean section, with weight of 3,980 g and Apgar score 9-9 in conventional time. Newborn presented a maxim bilirubin level of 16 mg, controlled with phototherapy; the hepatic function was normal. Ultrasound showed a choledocal cyst which measured 50 x 49 x 48 mm, with dilatation of the hepatic common conduct, the gall bladder was normal. The abdominal scan reported a cystic mass in the middle abdominal region of 44 x 53 x 52 mm confirming a choledocal cyst. The diagnosis was confirmed after surgery. Patient had a satisfactory post-surgical evolution.
