Tc-99m MAG3 renography in renal vein thrombosis secondary to Finnish-type congenital nephrotic syndrome

Scintigraphic findings in renal vein thrombosis (RVT) have been well described on studies performed with Tc-99m DPTA, Tc-99m glucoheptonate, and I-131 ortholodohippurate. The authors could find no reports of RVT findings on Tc-99m mercaptoacetyltriglycine (MAG3) imaging. Tc-99m MAG3 renal scintigraphy in an infant with RVT because of Finnish-type congenital nephrotic syndrome is described. Correlative ultrasound and inferior vena cava venogram findings are presented.
