title: Adult Wilms tumor and polyarteritis nodosa. Overlapping arteriographic findings.
abstract: We report a case of spontaneous renal hemorrhage that arteriographically appeared to be polyarteritis nodosa but which in fact turned out to be a malignant process. This case stresses the overlapping arteriography of two disease processes and emphasizes the need for tissue diagnosis since radiographic findings may not be as specific as has been reported.
