title: Polyarteritis nodosa with renal artery stenosis.
abstract: Renal angiographic signs in Polyarteritis Nodosa (PAN) vary from aneursyms of medium and small vessels, perfusion defects and delayed emptying of renal arteries. These vascular changes are usually responsible for the hypertension. In this case study stenosis of a main renal artery, an unusual finding in classical PAN, is believed to be the cause of hypertension. Hence renal angiography is essential to define the renal vascular changes and confirm the cause of hypertension.
