1 Correlation between temporal pole MRI abnormalities and surface ictal EEG patterns in patients with unilateral mesial temporal lobe epilepsy  Luís Otávio S.F. Caboclo, Eliana Garzon, Pedro A.L. Oliveira, Henrique Carrete, Ricardo S. Centeno, Marino M. Bianchin, Elza Márcia T. Yacubian, Américo C.

2 Figure 1 The arrow marks ictal onset characterized by rhythmic theta activity over the right temporal region, clearly visualized in the sphenoidal electrode. Seizure - European Journal of Epilepsy  , 8-16DOI: ( /j.seizure ) Copyright © 2006 British Epilepsy Association Terms and Conditions

3 Figure 2 MRI coronal images. (A) IR sequence showing markedly atrophic left hippocampus and (B) FLAIR sequence revealing abnormal signal of left temporal pole, with loss of gray matter–white matter differentiation.

4 Figure 3 MRI coronal images. (A) FLAIR sequence showing atrophy and increased signal of the left hippocampus and (B) more anterior FLAIR sequence, revealing reduced left temporal pole.
