It is common in young women. Pathogenesis of Takayasu arteritis is characterized by granulomatous inflammation and fibrosis, especially in the medial layer of the arterial wall. Although a large number of patients with vasculitis do not show any increase in inflammatory markers, classically vasculitis is still considered a systemic inflammation with elevated acute phase reactants. Renal artery stenosis Renal artery stenosis is a common cause of secondary hypertension. It is an atherosclerotic condition that eventually leads to renal failure due to renal hypoxia and inadequate nutrition of renal parenchymal cells caused by the stenotic artery. Atherosclerosis in the renal artery is almost always observed in the proximal to mid portion; in contrast to FMD which mostly occupies the mid to distal regions. Fibromuscular dysplasia Although FMD may be an incidental finding, it may present with hypertension due to alteration in renal hemodynamics. Secondary hyperaldosteronism Although secondary hyperaldosteronism may be a cause of secondary hypertension, the patient's findings are not consistent with secondary hyperaldosteronism. Pheochromocytoma Pheochromocytoma is also a cause of secondary hypertension in young patients. However, imaging in pheochromocytoma typically demonstrates a mass in the adrenal glands. Renal artery involvement is not likely in pheochromocytoma. Pathology C Renal 2020-10-28T00:08:37Z 2459150.5059838 WBR0309
