Examples of MRI features for the MTLE-HC group (a), the MTLE-CA group (b), and the MTLE-HC+CA group (c). (a) Upper row: (A) FLAIR and (B) T2-weighted coronal images showing on the right side enlarged amygdala with increased MR signal in FLAIR and T2-weighted sequences (dysplastic amygdala). Lower row: (C) FLAIR and (D) T2-weighted coronal images showing normal hippocampus; R: right hemisphere; L: left hemisphere. (b) Upper row: (A) FLAIR and (B) T2-weighted coronal images showing on the right side atrophic hippocampus with increased MR signal in FLAIR and T2-weighted sequences (hippocampal sclerosis). Lower row: (C) FLAIR and (D) T2-weighted coronal images showing normal amygdala; R: right hemisphere; L: left hemisphere. (c) Upper row: (A) FLAIR and (B) T2-weighted coronal images showing on the left side dysplastic hippocampus with increased MR signal in FLAIR and T2-weighted sequences. Lower row: (C) FLAIR and (D) T2-weighted coronal images showing on the left side enlarged amygdala with increased MR signal in FLAIR and T2-weighted sequences (dysplastic amygdala); R: right hemisphere; L: left hemisphere.
