The polyarteritis nodosa (PAN) is nongranulomatous disease of only medium sized arteries, the etiology of medium sized vessel vasculitis compatible with PAN is unknown, instead the predominance of neutrophils and mononuclear cells, with weakening of the vessel wall and aneurysm formation, causing stenosis and occlusion and finally myocardial infarct. Other finding in PAN are conduction system abnormalities and systemic arterial hypertension. There a few knowledge relationed in cardiac damage by PAN, as we can notice in a old study realized in the Mayo Clinic by a review of autopsy records for the period 1926 to 1958 involving cases of PAN, the studies the heart in 66 cases. In this patient we can distinguish fibrosis using late gadolinium enhancement were we found a patchy pattern as old studies showed by autopsy.
