CT appearance of global renal infarction.

The computed tomographic (CT) appearance of global infarction of the kidney has not been previously reported. We report a clinically proven case as well as two other cases with clinical and radiographic findings consistent with renal infarction. The CT appearance of global renal infarction corresponds with its conventional intravenous urographic appearance. A thin rim of perfused cortical tissue, supplied by collateral vessels, surrounds the nonperfused central renal parenchyma.
