Fibromuscular dysplasia (FMD) was a term introduced by McCormack et al1 to describe a rare non-atherosclerotic, non-inflammatory segmental occlusive disorder of medium-sized vessel arteries.2 The FMD may be intimal, medial or periarterial, depending on the site of fibro-muscular proliferation.2 Mesenteric arteries are uncommonly affected.
