140 patients with epileptic seizure were studid by computed tomograpy during the period from Feb. 1979 to Aug. 1979 in the Department or Radiology, College of Medicine, Hanyang University. Those findings's on CT and clinical records including EEG findings were reviewed. The results were as follows : 1. Age distribution of the total 140 patients was broad ranging from 1 month to 63 years. 73.5 % of patients was below the age of 30. The patient population was comprised of 93 males and 47 females, and its male to female ratio was 2 : 1. 2. The types of epileptic seizure were classified accordng to the International League against Epilepsy. 42.9% of patients had primary generalized seizure, 47.1% with partial seizure, and 10 % with non-classifiable seizure. 3. As additional symptoms and signs except seizure, headache was most common, and the next was nausea and vomiting. Uncommonly, there were also insominia, personality change, and memory disturbance. 4. 37.1% of patient had less than 1 month of seizure history, 19.3% between 1 year and 5 years. 5. EEG findings were available in 41 patients, and normal in 15 cases. 26 patients revealed abnormal findings. Among those abnormal findings focal slowing was appeared in 19.5% and generalized slowing in 17.1%. 6. 52% of patients showed abnormal findings on CT, The most common abnormal findings was focal low density (30%), and the next was diffuse hydrocephalus(7.1%). After contrast infusion, contrast enhancement was occured in cases with focal low density, focal high or isodense mass density. In patients with focal low density, ring or nodular enhancement were common, and diffuse or serpentine enhancement infocal high or isodense mass density. 7. The frequency of structural abnormalities in CT was more common in patients below the age of 10 and over 30 than other age groups. The epiepsy starting below 10 and over 30 years of age showed structural abnormalities in 63.6-100%. 8. The patients who had less than 6 months f history revealed more abnormal findings than the patients with over 6 months of history. And most of the abnormal findings in the latter were atrophic lesion. 50% of patients with primary generalized seizure and 54.5% of patients with partial seizure revealed abnormal findings on CT. 9. EEG was done in 41 cases, 23 out of 41 patients revealed normal CT and 18 patients revealed abnormal CT. In patients with normal EEG, 9 patients revealed abnormal findings on CT. 8 out of those 9 patients showed focal low density, So, there was no significant correlation between EEG and CT. 10. Most of the lesions on CT were located in the supratentorial region, particularly in the frontal and parietal lobe. There were patients who had lesions in the posterior fossa, one in the brain stem and the other in the vermis. 11. The diagnosis bases on the CT findings included brain tumor(9.3%), cerebral infarct(7.9%), granuloma(5.7%), cortical atrophy(5%), and calcification (5%) respectively.
