Figure 11A. Axial T2W FSE image at the level of the basal ganglia. Possible signal abnormality in the right insula is noted (arrows).

Figure 11B. Axial FLAIR image, same level as A. Signal abnormality is confirmed in the right insula (arrowheads); also, subtle FLAIR signal is present in the left insula (arrow).

Diagnosis: Herpes encephalitis.

Discussion：Case 11 is a case of a young patient with altered mental status; the possible right insular signal abnormality on the T2W image is confirmed on FLAIR as the suppression of CSF results in improved contrast between normal and abnormal

parenchyma. The FLAIR image also revealed a subtle abnormality in the contralateral insula, which was undetectable on the T2W image. The finding of bilateral, asymmetric parenchymal abnormalities in this patient with altered mental status raised the possibility of herpes encephalitis, which was confirmed on subsequent CSF studies.
