Prenatal diagnosis of congenital mesoblastic nephroma: a case with poor prognosis

Abstract

Congenital mesoblastic nephromais a rare tumour found in neonates, with a very small number of cases diagnosed prenatally. We report a case of a fetal renal tumour suspected at 28 weeks’ gestation on routine ultrasound. Prenatal follow-up revealed a severe polyhydramnios at 32 weeks’ gestation subsequent amniodrainage was undertaken. She delivered at 34+5 weeks’ gestation, after spontaneous premature rupture of membranes.
