Objectives: Ovarian cysts are frequently find in fetuses and neonates. The optimal management of neonatal simple ovarian cysts is still a matter of discussion.
Materials: Authors present four cases of neonatal ovarian cysts treated in Pediatric Surgery Clinic of Medical Academy in Bialystok in the period of 2002-2003. Three girls were managed conservatively--they are still in outpatient care. One girl was managed surgically.
Conclusions: The main aim of treatment is to preserve the ovary. Uncomplicated prenatal ovarian cysts should be treated depending on size and echographic patterns at birth.
