Prenatally diagnosed cystic XXXX : a report of two cases.

@entity1 @entity3928 @entity5 @entity521
We report two cases of prenatally diagnosed cystic @entity521 (PDCN). In the first case, prenatal ultrasonography (US) at 33 weeks' gestation showed a 30 x 20 mm cyst at the upper pole of the right kidney. The size and content of the mass demonstrated no change during pregnancy. Postnatal US showed no change in the @entity3928 4 weeks after birth compared to the prenatal findings. The @entity1 underwent total resection of the @entity5 at 28 days of age. In the second case, a left @entity3928 measuring 50 x 40 mm was detected in a fetus in the 37th week of pregnancy. Postnatal US showed a @entity3928 in the left adrenal gland. The US findings showed no change 18 days after birth and the @entity1 underwent total resection of the @entity5 at 19 days of age. In both cases, pathological examination revealed a @entity521 and all of the biological prognostic factors were favourable. Surgical intervention was necessary for a final histological and biological diagnosis to be made. We recommend that prenatally suspected @entity521 should normally undergo surgical intervention, unless @entity5 size decreases within about 1 month after birth.
