The brain computerized tomography, an epoch-making diagnostic procedure has caused a revolutionary change in the neurosurgical field;the correct localization of small space occupying lesion wherever it is in the brain without pain and harm to the patients. The brain CT findings of 3035 patients which were examined in this hospital during past 29 months from Oct. 1981 to March 1984 were analysed and the literature review was made. The results of analysis are as follows: 37.1% of total 3035 cases were observed abnormal, including 29% of head injured patients, 42.4% of non-trauma cases, 57.6% of emergency cases and 15.2% of non-emergency cases. 2) The rates of abnormal findings were proportional to the degree of consciousness disturbance in the head injured patients and severity of the neurological deficits in the other neurosurgical patients. 3) The follow up studies were performed for 287 patients among 1127 patients having abnormal findings in the first check and we found the improving process of various lesion and the resolving process of hematoma after operation. The follow up studies were performed for 138 patients having normal findings in the first check and 26% of these cases were observed abnormal, including 21.5% of head injured cases and 55% of the non-trauma cases. 4) 94% of patients with spontaneous subarachnoid hemorrhage showed bleedings chiefly in the basal cistern.
