Résumé
Classical dual pathology is the coexistence of temporal mesial sclerosis (TMS) and an ipsilateral extra-hippocampal lesion. The aim of this presentation is to increase the awareness of the existence of this pathology as well as variants as a cause of refractory temporal lobe epilepsy and its difficult pre-op diagnosis. Of the 32 cases here presented, 19 were adults and 13 children. Adults: 17 had TMS + cortical dysplasia (CD) and of the remaining patients, 1 had TMS + oligodendroglioma and 1 TMS+ ganglioglioma. Children: pathology findings were: A) TMS + malformation of cortical development 6; B) TMS + CD + ganglioglioma 2; TMS + ganglioglioma + post-infectious sequelae 1 (triple pathology) and C) CD associated with low-grade glioma 1 and with MAV 1.Surgical techniques: LATS and the Spencer variant were the most commonly used techniques. Results: Patients in both groups are in Engel Class I and II. Conclusion: The good results in this series can be attributed to the complete resection of these entities.
