title: [Comparison of the EEG and computerized tomography findings in 500 patients hospitalized in the neurology clinic of the Salpêtrière].
abstract: A comparative EEG and CT scan Study of 500 inpatients was performed. Patients were divided into four groups: 82 patients (16.5%) had normal EEG and CT scan; 92 patients (18.5%) had normal EEG but abnormal CT scan; 75 patients (15%) had abnormal EEG and normal CT scan; 251 patients (50%) had both EEG and pathologic CT scan alterations. Among the 500 patients, 326 EEG (65%) and 343 CT scan (69%) were abnormal. In 167 cases (33%) only one examination was abnormal. This finding may be considered as indicative of the complementary role for both techniques. For each group, the main clinical features were underlined: objective neurologic syndrome, seizures, psychiatric conditions, subjective complaint and headache. In groups with a pathologic CT scan and pathologic EEG, a percentage of 74 showed a clear neurological nosology. In 41% of these patients, lateralisation and localisation were much easier, owing to the presence of a single lesion. This study emphasised that electroencephalography is useful in temporal pathologies and in determination of the epileptic frame, whereas CT scan is useful in subcortical lesions in fronto-parietal lesions.
