[The periarteritis nodosa--diagnosted by angiography. A case with multiple aneurysms (author's transl)].

Periarteritis nodosa is a severe systemic disease which is characterized by an inflammation of the vessel walls and a high incidence of renal involvement. Angiography should be performed immediately when clinical suspicion is aroused. Angiography is superior to the results of skin and muscles biopsy and gives information about the extension of the disease.
