Acute perfusion MR imaging in a HaNDL-like syndrome.

摘要

A 44-year-old right-handed man, with no history of migraine or cardiovascular risk factors, developed acute numbness and weakness involving the right leg and ascending to the right arm and the face, with aphasia and right homonymous hemianopsia. The symptoms cleared within 8 h.Cerebral MR imaging performed 2 h after the onset of symptoms - including T2 diffusion-weighted fluid-attenuated inversion recovery (FLAIR) images, MR angiograms (time of flight: cerebral and cervical) and perfusion analysis (time to peak map, cerebral blood volume, cerebral blood flow) - revealed a global left-hemispherical hypoperfusion. The mean time-to-peak delay in the affected hemisphere versus the contralateral side was 2.5 s. The cerebral blood flow ratio was 0.71
