Abstract

An 83-year-old woman presented with acute aphasia. Brain MRI, performed 3 hours after symptom onset, showed isolated fluid-attenuated inversion recovery vascular hyperintensities (FVH) in the left middle cerebral artery, including dot-like and serpentine hyperintensities (figure). Immediately after this first MRI (i.e., 3 hours and 15 minutes after symptom onset), aphasia resolved. A second MRI performed 15 minutes later showed FVH disappearance.

Figure. Vascular intensity changes on fluid-attenuated inversion recovery during and after resolution of symptoms in our TIA patient
Fluid-attenuated inversion recovery vascular hyperintensities (FVH) during aphasia, including dot-like (arrows in A and B) and serpentine (arrowheads in A) hyperintensities, were seen in the middle cerebral artery branches. There were no abnormalities on diffusion-weighted or gradient echo images or magnetic resonance angiography. After aphasia resolution, the MRI showed FVH disappearance (C, D).
