[Computerized transverse axial tomography in the diagnosis of epilepsy; an electroencephalo-tomographic study (author's transl)].
193 patients with epilepsy were investigated by EEG and by computerized tomography (C.T.). 55.5% of the pathological C.T. scans were found in partial seizures with elementary symptomatology. In patients with generalized seizures the diagnosis of symptomatic epilepsy could be made in 40 cases (35.7%) with the help of computerized tomography. In 38 EEG there was a continual delta-wave focus, 18 of these with epileptogenic activity. Of these 38 patients, 34 showed a pathological result in computerized tomography. 19 tumors or metastases, 11 cases of atrophy (10 local and one diffuse) as well as one case of encephalitis could be diagnosed. The remaining 3 patients showed indefinate findings with C.T. 19 EEG showed intermittent theta-wave foci. Computerized tomography gave 5 pathological scans in these patients. If one compares the results of computerized tomography and EEG in cases of tumor, the agreement between positive tomography and the pathological EEG is very high (95%): 64 positive C.T. compared with 61 positive EEG. Our investigations with computerized tomography show organic findings in 67 of 193 epilepsies, that is about 35%.
