Fibromuscular hyperplasia of arterioles
Fibromuscular dysplasia is a focal irregular thickening of the walls of medium-sized and large muscular arteries due to a combination of medial and intimal hyperplasia and fibrosis. It can manifest at any age but occurs most frequently in young women. The focal wall thickening results in luminal stenosis or can be associated with abnormal vessel spasm that reduces vascular flow; in the renal arteries, it can lead to renovascular hypertension. Between the focal segments of thickened wall, the artery often also exhibits medial attenuation; vascular outpouchings can develop in these portions of the vessel and sometimes rupture.
I thought this was a weirdly worded answer. I immediately ( stupidly) crossed of fibromuscular dysplasia since it wasnt a younger women =/
I was thinking malignant nephrosclerosis ... but I guess you'd get hyperplastic arteries first -_-
The answer choice is fibromuscular HYPERplasia - I think this is different from fibromuscular DYSplasia (seen in young women);
hello is right. Fibromuscular hyperplasia is thickening of the muscular layer of the arteriole in response to chronic hypertension (as the question stem implies)
