[Histopathology of 110 cortical resections for drug-resistant epilepsy]

Histopathologic findings in 110 cortical resections performed for medically intractable epilepsy are reported. The abnormalities observed in our series fell into seven categories: vascular lesions, tumors, non-vascular malformative lesions, focal accumulation of polyglucosan bodies, non infectious inflammatory lesions, hippocampal sclerosis, and mild non-specific lesions. There was no microscopic abnormality in 14 cases. Several patients presented a double pathology, most often an hippocampal sclerosis as one part of the dual pathology.
