The 27 year-old patient with unremarkable family and environmental anamnesis presented at 15+5 weeks of pregnancy (biometry equivalent to 16+6 weeks). Ultrasound revealed an abdominal anechoic round cyst in the upper abdomen close to the porta hepatis. The patient presented again at 24 weeks. At this time the cyst was no more round. There were two tubular structures projecting from the round part of the cyst directed anteriorly and to the right, which probably represented dilated bile ducts. The growth of the cyst was relatively proportional to the growth of the fetus.
The patient was subsequently rescanned on several occasions, the last time at 35 weeks and there were no significant changes in the appearance of the lesion.
The baby was born on term, and postnatal ultrasound and scintigraphy of the liver confirmed the supposed diagnosis of the choledochal cyst. Clinically and on the basis of laboratory tests the baby does not require surgery yet, but he is under periodical supervision.
