TORRES, Carolina et al. Unilateral hippocampal sclerosis with subdural strips in seizures from the contralateral temporal lobe: case report. J. epilepsy clin. neurophysiol. [online]. 2006, vol.12, n.2, pp. 95-98. ISSN 1980-5365. http://dx.doi.org/10.1590/S1676-26492006000300009.
INTRODUCTION: Most patients with temporal lobe epilepsy and hippocampal sclerosis have the seizures and the interictal electroencephalographic abnormalities coming from the side of atrophic hippocampus. Even some patients on whom the seizures seem to arise from the contralateral temporal lobe, invasive recordings have shown that the seizures actually come from that atrophic side. But this may not be always the case. OBJECTIVE: We report a patient with a unilateral hippocampal atrophy and the seizures, seen both on the scalp as well with subdural strips, come from the contralateral temporal lobe. A patient with right hippocampal atrophy had most of the interictal discharges coming from the left temporal lobe, as well her seizures. Invasive recordings with subdural strips also showed seizures arising from the left temporal lobe. CONCLUSION: There might be some patients with temporal lobe epilepsy whose seizures come from the less.
