A brain CT with perfusion imaging performed 1 h 54 min after symptom onset revealed a prolonged mean transit time (MTT), i.e., a hypoperfusion in the right frontal lobe reaching to the parietal lobe (Fig. 1a, b). Brain magnetic resonance imaging (MRI) performed 5 h 46 min after symptom onset (Fig. 1c, d) revealed diffusion restriction (Fig. 1c) in the same area as the hypoperfusion on CT (Fig. 1b). T2 images (Fig. 1d). The patient stayed fully recovered, except for reduced sensation for all modalities on the extremities on the left side.
Non-contrast brain CT 24 h after symptom onset.

A new brain CT 24 h after symptom onset revealed an edema in the same area as the hypoperfusion seen on the perfusion images at admission (Fig. 2).
a MR diffusion 18 days after symptom onset. b MR T2 axial 18 days after symptom onset.
