[Radiological study of panarteritis nodosa with renal localization. Considerations on 9 cases].

The pathologic lesions in panarteritis nodosa with renal involvement are of two types: macroscopic and microscopic. The diagnosis of the macroscopic form is made with angiography when it discloses diffuse aneurysms. The angiographic features of the microscopic form are not distinguished from those of other renal parenchymal diseases. Plain films of the abdomen and urography are insufficient for diagnosis but they can be useful in the follow up of the panarteritis nodosa.
