In my opinion, the diagnosis is probably idiopathic arteritis or panarteritis instead, although no mention was made of this syndrome in their discussion.The diagnosis in their case was made on the basis of biopsy findings and limited arteriograms. A biopsy specimen of one of the temporal arteries showed intimal fibrosis and chronic inflammatory changes in the media and adventitia.

The renal biopsy specimen demonstrated changes that were consistent with polyarteritis.Because of the limited nature of the diagnostic studies, the full extent of their living patient's disease could not be determined.
