[The problem of neuroroentgenologic diagnosis of an epileptic focus in so-called temporal lobe epilepsy]

The size of individual elements of temporal cornua of the lateral ventricles of the normal human brain has been determined. The topic diagnostic informative value of preoperative pneumoencephalography has been found inadequate for determining the degree of morphological alterations in the mediobasal brain structures. On the basis of the findings from preoperative pneumoencephalograms and operative positive ventriculograms of 80 patients the author has demonstrated the necessity of a detailed ventriculographic examination of the brain using the technique of orthogonal teleroentgenography and administration of positive contrasting agents. The ventriculographic criteria for locating the epileptic focus, verified by stereoelectroencephalographic studies, have been described.
