title: [Prenatal ultrasonographic diagnosis of a cystic ovarian tumor].
abstract: Clinically important ovarial cysts are extremely rare in the female foetus and newborn. About 70 cases only have been published so far. There are only four reports on antepartally diagnosed ovarial tumours. The article reports on the prenatal ultrasonographic diagnosis of a foetal ovarial tumour in the 34th week of pregnancy. Diagnosis "on suspicion" was substantiated by the identification of an intact and properly functioning foetal urogenital system and no abnormal findings in the intestinal organs, as well as by the identification of the sex of the foetus. Differential diagnosis in all cases of cystic foetal space-occupying tumours should consider, in the first place, malformations of the urogenital system, cysts of the liver, pancreas and mesenterium, as well as disturbances of function or malformations of the foetal digestive tract.
