ABSTRACT
BACKGROUND:
Spontaneous subclavian artery dissection (SAD) is rare. Moreover, there are very few case reports which document spontaneous SAD accompanied by symptomatic neurological deficits related with ischemic stroke. CASE REPORT A 71-year-old man without any reported history of trauma presented with left facial hypesthesia, left arm ataxia and gait disturbance, subsequently diagnosed as posterior circulation infarction affecting medulla and cerebellum. The computed tomography angiography revealed spontaneous left SAD with left vertebral artery occlusion, atherosclerotic plaque surrounding the origin of left subclavian artery and normal aortic vasculature. His neurological status did not deteriorate further after dual anti-platelet therapy, and intravenous hydration with volume expander were applied.CONCLUSIONS:
This is an unusual case of spontaneous SAD with lateral medullary infarction as well as cerebellar infarction. Although spontaneous SAD is a distinctly rare disease entity, it should be considered in the differential diagnosis when multiple posterior circulation infarctions are observed.Key words
