title: Polyarteritis nodosa complicated by posterior reversible encephalopathy syndrome: a case report.
abstract: Hypertension (HT) represents a major public health problem affecting many individuals worldwide. It is well known to be an important risk factor for the development of cerebrovascular and cardiovascular diseases. Classifying hypertension as &lsquo;primary&rsquo; or &lsquo;secondary&rsquo; depends on the underlying mechanism. In 5 to 10% of hypertensive patients, HT develops &lsquo;secondary&rsquo; to a separate mechanism that has been encountered with increasing frequency in the tertiary refferral centers. The frequent causes of secondary hypertension include renal parenchymal disease, renal artery stenosis, primary hyperaldosteronism, phaeochromocytoma and Cushing's syndrome. Polyarteritis nodosa (PAN) can involve any organ and in varying degrees. Here we present a young hypertensive patient diagnosed as PAN with the angiographic findings of multiple microaneurysms involving celiac, renal and superior mesenteric arteries and associated with a rarely seen neurological entity-PRES syndrome.
