Female, 25 years old, with history of HSV encephalitis. Compare to prior exam. Since the prior exam, encephalomalacia has developed in the left anterior temporal tip, amygdala and hippocampal head. The surrounding tissue demonstrates FLAIR hyperintensity compatible with gliosis which extends up into the insula. Ex vacuo dilatation of the left temporal horn is seen. The remainder of the brain is unremarkable. No new signal abnormality is seen. No pathologic parenchymal enhancement is detected. There is no evidence of intracranial hemorrhage or any abnormal collection. Except as above, the ventricles are within normal limits.
Findings compatible with chronic evolution of HSV encephalitis of the left temporal lobe. No new or active intracranial lesions are suspected.
