Resumo

Mesial temporal lobe epilepsy is the most commom form of focal epilepsy in adults. Its clinical features include focal seizure, dysmnestic symptoms – such as déjà vu or jamais vu – and autonomic or psychic aura. We reported two cases of mesial temporal lobe epilepsy with similar clinical features, but with entirely different etiologies. Mesial temporal sclerosis contributes up to 70% of all mesial temporal lobe epilepsy cases and MRI usually shows reduced hippocampal volume and increased signal intensity on T2-weighted imaging. Incomplete hippocampal inversion has uncertain relation with epilepsy and is characterized by an atypical verticalized and medially positioned anatomical pattern of the hippocampus and also a deep collateral sulcus.
