FIG 5. Coronal MR images of a 32-year-old man with cryptogenic right TLE. The duration of epilepsy at the time of imaging was 29 years, and the seizure frequency was 36 complex partial seizures per year. The patient subsequently underwent surgery and is currently seizure-free (Engel's class IA).
A, Ipsilaterally, the volume of the entorhinal cortex is 81% of that (mean volume) in control subjects and 78% of that on the contralateral side.
B, MR image taken from a more caudal level shows the volume reduction in the ipsilateral hippocampus (volume 41% of that in control subjects and 50% of that on the contralateral side). The volume of right perirhinal cortex is 2597 mm3; left, 2924 mm3 (both within normal range). A indicates amygdala; EC, entorhinal cortex; HC, hippocampus; L, left; PRh, perirhinal cortex; R, right. Scale bar, 10 mm.
