Abstract
An 87-year old man with hypertension, diabetes, and renal failure was admitted with aphasia and right-sided weakness. Susceptibility-weighted imaging (SWI) revealed prominent vessel sign (PVS) without an acute lesion, with left carotid artery occlusion and decreased perfusion of the left hemisphere. The blood pressure increased from 90/60 mmHg to 160/80 mmHg after hypertensive treatment and the neurological deficits recovered completely. Five hours later, the PVS decreased on follow-up SWI. The PVS dynamically changes according to the perfusion status; therefore, it may be potentially beneficial to evaluate the perfusion status after treatment, especially in patients in whom contrast agent use is contraindicated.
