Disorganization of cortical structure and the brain tumors.

In the course of histopathological investigation of the temporal lobe sections, selected from 63 patients treated surgically for intractable epilepsy and finally presented with primary temporal tumors, we found 12 cases expressed both neoplastic process' and developmental disorders. The temporal mass lesions consisting of neuro-glial or pure glial tumors were associated with some developmental abnormalities such as cortical dysplasia, neuronal heterotopias and additional cortical neoplastic nodules. The possible "dual pathology" concerning these lesions are discussed in this paper.
