Radionuclide imaging and angiography. Both iodine-123 metaiodobenzylguanidine (A) and gallium-67 (B) scintigraphies were negative in the mass, whereas thallium-201 mildly accumulated in the tumor below the right kidney (C, arrow). Positron emission tomography was positive in the tumor at a standard uptake value of 4.7 without any other abnormal uptake in other parts of the body (D). Digital subtraction angiography revealed abundant vascularity of the tumor (E, arrow). Feeding vessels from the right lumbar arteries were embolized with porous gelatin particles (F).
