Answer

Answer

Usually, lymphoma is a hypovascular neoplasm; therefore, angiography cannot help in the diagnosis or staging of lymphomatous tumors. Thus, with contrast-enhanced CT scanning, the lesions remain hypovascular compared with the renal parenchyma when the contrast material is delivered to the kidney, via either intravenous injection for CT scanning or direct arterial injection for angiography. Therefore, the degree of confidence with angiography is low, and the degree of false-negative findings is high.

The degree of confidence is low in the diagnosis of renal lymphoma with angiography. False-negative diagnoses occur at a high rate.
