FIG 2. Coronal view fast spin-echo T2-weighted images (2975/98) of an 11-year-old female patient who had experienced complex partial seizures since the age of 4 years after prolonged febrile convulsions during infancy. At age 12 years, the patient underwent a temporal lobectomy. Histologic examination showed hippocampal sclerosis, with no dysplasia in the temporal specimen.

A and B, Subtle asymmetry of signal intensity in the white matter of the left temporal pole compared with the right (arrows) is shown, with apparent shrinkage of the white matter due to the slightly increased white matter signal intensity. The appearances on coronal view T1-weighted fast spoiled gradient-recalled volume acquisition images were normal.

C, More posteriorly, right hippocampal sclerosis is shown (arrow), with normal signal intensity within posterior right temporal white matter.
