The diagnostic value of computerized axial tomography (CAT) in focal epilepsy.

The material of the Computerized Tomography Laboratory of the Institute of Radiology in Poznań concerning patients with focal epilepsy deals with more than 200 cases. In this paper we present 84 cases with verified etiology in the Neurosurgical Department. There were 39 cases of partial epilepsy of simple symptomatology, 28 cases of partial epilepsy with complex symptomatology (temporal) and 12 cases of secondary generalized epilepsy. CAT performed in 62 patients proved to be most adequate in the brain tumors and in atrophic lesions, than posttraumatic and postinfective lesions, less valuable in vascular diseases and degenerative processes.
