title: Vicarious liver visualization in solitary functioning kidney with technetium-99m ethylenedicysteine renal scintigraphy.
abstract: We present a case of 3-year-old boy who was incidentally diagnosed to have single left kidney on ultrasonography. Dynamic technetium-99m ethylenedicysteine renal scintigraphy was acquired for assessing the existing kidney function showed the tracer localization in bilateral renal fossae during the entire study. The single-photon emission computerized tomography/computerized tomography study revealed activity in the right renal fossa to be in the enlarged right lobe of the liver, which was mimicking as impaired functioning right kidney in planar images. The hybrid imaging helped in accurate delineation of tracer uptake by confirming it to be the false appearance of the right kidney in planar imaging. This case report also highlights the possible mechanism of renal tracer uptake in the liver parenchyma.
