Abstract
Fluid-attenuated inversion recovery (FLAIR) hyperintense vessel (HV) sign is usually seen in patients who has steno-occlusive lesion in intracranial artery, as it reflects the decreased arterial blood flow velocity. A 79-year old male patient, who had multiple cerebral infarctions, showed FLAIR HV signs on both middle cerebral artery territory without any steno-occlusive lesion in initial magnetic resonance angiography (MRA). However, follow-up MRA showed decreased bilateral middle cerebral artery branches and distal stenosis. In our case, bilateral FLAIR HV sign without steno-occlusive lesion might be used as a poor prognostic factor indicating progressive arterial occlusion.
