Tc-99m glucoheptonate scintigraphy in a case of renal vein thrombosis

Tc-99m glucoheptonate flow and static studies with computer-assisted analysis provided specific diagnostic information in unilateral renal vein thrombosis complicating a case of nephrotic syndrome. Decreased flow with congestion, a large kidney with parenchymal thickening, pelvocalyceal thinning, good function, and no obstruction in the proper clinical settings indicated the diagnosis of a chronic form of renal vein thrombosis with compensating collateralization. The differential diagnosis is discussed.
