Prenatal calcification of the inferior vena cava and renal veins in a normal neonate.

Abstract

Prenatal calcification of the inferior vena cava (IVC) and renal veins is a rare condition with unclear etiology and prognosis. It occurs with renal vein thrombosis in utero and is associated with congenital anomalies and abnormal prenatal hemodynamic status. We report a rare case of prenatal IVC and renal vein calcification in a normal neonate without any history of compromised prenatal or perinatal condition, or significant deterioration of kidney function.
