Congenital true pancreatic cysts are quite rare in the children. Fetus, which shows an intraabdominal cystic mass in ultrasound (US) performed during the antenatal examination, was delivered at a gestational age of 37 weeks. As a result of the histopathological examination, pancreas-originated cystic mass with the dimensions of 8x5x1cm, which has been totally excised during the operation was reported to be a congenital true pancreatic cyst. This rarely seen entity, which has been diagnosed during the neonatal period before the occurrence of any clinical signs and which has been successfully treated, was presented along with the literature.
