description Congenital renal tumors are rare. In infancy, congenital mesoblastic nephroma is the most commonly reported renal tumor. It is recognized antenatally due to polyhydramnios and presents clinically as a palpable abdominal mass in the neonatal period. Although widely regarded as a benign tumor, radical nephrectomy is routinely adopted as an effective treatment. We report a case involving antenatal recognition of a large fetal renal mass with polyhydramnios at 35 weeks of gestation. At 37 weeks of gestation, the baby was delivered via emergency cesarean section due to fetal distress. After delivery, a magnetic resonance imaging scan confirmed a solid mass in the left kidney, and a left radical nephrectomy was performed in the second week of life. The subsequent pathological examination confirmed a mixed (cellular and classical) variant of congenital mesoblastic nephroma.
