title: Renal complications of polyarteritis nodosa: CT findings.
abstract: Three patients with multiple renal complications of polyarteritis nodosa are described. The arteriographic findings in these patients were multiple arterial aneurysms and tissue infarctions, with the development of spontaneous intrarenal, subcapsular, and perirenal hemorrhagic complications. Computed tomography showed the hemorrhages and multiple renal infarcts; acute and late forms could be differentiated on the basis of contrast medium enhancement and scar formation.
