Mesoblastic nephroma is by far the most frequent intrarenal fetal tumor. To the best of our knowledge, we report the first case of a newborn with an intrarenal neuroblastoma that was discovered prenatally. An intrarenal echogenic and homogenous mass was observed on routine prenatal ultasonography, corroborated by magnetic resonance imaging, in a 30-week gestation fetus. A male weighing 3280 g was born with elevated blood pressure and cardiac failure. Postnatal ultrasound confirmed a left intrarenal tumor with microcalcifications and perirenal adenopathy.
