Computed tomography in adult-onset epileptic seizures in a city hospital population.
Computed tomography (CT) was performed on 155 patients from a city hospital population who developed seizures after age 20. CT was normal in 58 (37.4%) and abnormal in 97 patients (62.6%). A focal abnormality was seen in 71 patients (45.8%). Lesions potentially correctable by surgery were found in 24 patients (15.4%). As expected, the occurrence of abnormal CTs was higher (73%) in patients with partial seizures. Although CT is undeniably useful in evaluating the cause of seizures, no demonstrable lesion was found in a relatively large number of patients (37.4%).
