Abstract
|
|
|
|
A 78-year-old right handed man with hypertension presented with sudden onset dysarthria and right hemiparesis. Magnetic resonance angiography revealed near-occlusion of left proximal internal carotid artery. Emergent carotid stenting was performed. On the 17th day after carotid stenting, he showed decreased consciousness. Magnetic resonance imaging (MRI) showed edematous change with high signal and increased perfusion in the left hemisphere. Our case shows that delayed cerebral hyperperfusion syndrome can occur even 2 weeks after carotid artery stenting and multimodal MRI can help accurate diagnosis.
