Symptoms of Fibromuscular dysplasia

Symptoms of Fibromuscular dysplasia

Fibromuscular dysplasia is an idiopathic noninflammatory arterial wall disease that typically involves small- to medium-sized vessels. It may be discovered incidentally, but it most commonly presents with hypertension, most often affecting young or middle-aged women.

On CTA and MRA, FMD classically resembles a “string of beads” with alternating areas of luminal narrowing and dilation, and it affects the renal arteries bilaterally in ≈40% of cases. FMD typically involves the mid or distal portions of the main renal artery, whereas atherosclerosis typically involves the proximal or ostial portions of the main renal artery and usually affects older patients. The stenotic lesions in FMD that lead to hypertension respond favorably to angioplasty.
