RESUMO
This study describes the usefulness of fluid-attenuated inversion recovery (FLAIR) pulse sequence for early diagnosis and treatment of herpes encephalitis. An 8-year-old boy with suspected herpes simplex encephalitis was examined by magnetic resonance imaging at 3 days post-symptom onset. Lesions in the right thalamus and insular cortex were detected by conventional T2-weighted images and images from FLAIR pulse sequence. Bilateral temporal lesions, however, were only detected by FLAIR images.

A 3-month-old male presented with right-side-dominant focal seizures. Focal spikes were observed on the left side of an electroencephalogram obtained at the time of onset. The immature development in the left middle temporal lobe was observed by initial magnetic resonance imaging (MRI). The hypoperfusion in the left temporal lobe observed with single-photon computed tomography was consistent with MRI findings. These MRI findings were not observed in a second MRI at 11 months of age. This observation may explain one of the causes of infant-onset focal epilepsy.
