Brain MRI performed 10 days after symptom onset showed restricted diffusion within the entire cortical ribbon over the left hemisphere on DWI sequences (A) and increased signal within the same distribution on FLAIR (C). No abnormality was definitively seen on ADC maps (B and E), possibly due to the low resolution of ADC sequences or to the likelihood that the abnormal signal on diffusion and FLAIR sequences is not related to ischemia. A follow-up MRI, performed 5 months after symptom onset, showed normalization of the DWI (D) and FLAIR (F) sequences.
