Cross-sectional imaging also plays a major role in diagnosing other vascular conditions manifesting with unilateral neck pain and mimicking IC, such as arterial dissection, large vessel arteritis, arteriosclerosis, fibromuscular dysplasia, or aneurysms.
Included in the differential diagnosis are inflammatory arteritis, collagen vascular disease, mycotic aneurysms, cystic medial necrosis seen in type IV Ehlers Danlos and Marfan's syndrome, and fibromuscular dysplasia (FMD) which are also important to consider [6, 7].
In our patient there was circumferential narrowing involving post ductal part of descending aorta and similar changes were seen in subclavian and left common carotid artery suggestive of Takayasu Arteritis with fibromuscular dysplasia. Her ejection fraction was 60%.No other associated anomaly was found.
Kim also notes that SCAD is more common in people with fibromuscular dysplasia (FMD), which causes some arteries to narrow and others to develop an aneurysm--a bulge that can weaken the walls of a blood vessel.
