Abstract

During last 3 years, we experienced 24 cases of acute seizure disorder, showing localized low density on computed tomographic (C-T) scan and having the clinical characteristics, and have analyzed clinically. The results were followings: 1. It was commoner in men, with a ratio of 2:1, and their ages ranged from 4 to 54 years (mean 20.9 years), with the peak incidence in 2nd & 3rd decades. 2. It occurred in any season, but commoner in summer and autumn. 3. This disorder was characterized by sudden onset of convulsion, focal or generalized, in health man, and had no other associated symptoms. 4. C-T brain scan showed decreased density without mass effect on parietal or frontal area, which had usually constrast enhancement such as small ring or nodular type, and disappeared between 3 to 5 months. 5. Other laboratory tests were normal except leukocytosis (11 of 18 cases) and abnormal EEG (9 of 24 cases). 6. This disorder was self limited. The cause was unknown, but it had the possibility of viral infection.
