Horseshoe kidney associated with anomalous inferior vena cava.

Horseshoe kidney associated with anomalous inferior vena cava is a rare congenital anomaly. Radiological demonstration of this combined anomaly is also uncommon, with only two cases of preisthmic inferior vena cava with horseshoe kidney in the imaging literature. We report a case of simultaneous horseshoe kidney and inferior vena cava lying anterior to the right renal moiety diagnosed by ultrasound and computed tomography.
