Psoriasis, sacroiliitis, and aortitis: an echocardiographic mimic of aortic root dissection.
A patient with psoriasis, HLA-B27-positive sacroiliitis, and aortitis presented with clinical features suggesting acute aortic dissecting aneurysm. Although M-mode and two dimensional echocardiography supported the diagnosis, dissection was excluded by angiography and by direct observation at surgery. Asymmetric thickening of the right coronary cusp secondary to psoriatic aortitis was found to be etiologic of both the regurgitation and the false-positive echo for dissection. It is emphasized that in the setting of any fibrocalcific or inflammatory disease of the aorta, the echo diagnosis of dissection is fraught with hazard.
