A stroke mimic with left-hemispheric leptomeningeal vessel paucity and hypoperfusion

Abstract

In the neuroimaging workup of a suspected ischemic stroke, the involvement of more than one arterial territory without an anatomical substrate should raise the suspicion of a stroke mimic. We report the case of a 61-year-old male with a new-onset headache and transient phasic disturbances who presented a pattern of vascular abnormalities characterized by left-hemispheric leptomeningeal vessel paucity and hypoperfusion.
