Fluid-Attenuated Inversion Recovery Vascular Hyperintensities in Transient Ischemic Attack within the Anterior Circulation

Figure 2

Fluid-attenuated inversion recovery vascular hyperintensity in a patient with left middle cerebral artery severe stenosis (M1). (a) MRA showed severe stenosis of the left MCA M1. (b) Dot-like and serpentine hyperintense signal of the middle cerebral artery branches in the left Sylvian fissure and the sulci of the left fronto-parietal lobes (arrows). (c) CT perfusion imaging showed severe hypoperfusion with prolonged MTT and decreased CBF and CBV values in bilateral cortical border zones and the left side of MCA territories.
