Eine isolierte fetale Nierenzyste als ein Zeichen für ein kongenitales Neuroblastom

Abstract

As a normal scan at 20 weeks of gestation a pregnant woman was referred at 36 weeks because of a cystic tumour in the fetal kidney. The cyst, 27 mm in diameter, was localised at the cranial pole of the right kidney. A fetal neuroblastoma was suspected. At the fourth day after birth adrenalectomy was performed and the histological finding confirmed the prenatal diagnosis. Two years later the child is healthy. In review of the literature we found that sonographic pattern and localisation of fetal neuroblastoma are different, but in all cases the detection was performed in the third trimester of gestation.
