Intracranial tuberculomas have been reported occasionally, especially in Asia, though much decreased in recent years. Those lesions can be diagnosed more easily and acurately using Computed Tomography (CT) than conventional method, including angiography. Authors analysed CT findings of 21 cases, confirmed as tuberculoma, at Hanyang University Hospital from May 1979 to June 1983. The results were as follows: 1. Of all 21 cases, multiple lesions were seen in 14 cases (67%) and single in 7 (33%). 2. Of all 21 cases, lesions located only at supratentorial were in 19 cases (90%) and remained 2 (10%) had lesions at both supra and infratentorial area. And temporal and parietal lobes were common location (65%) of all lesions. 3. In precontrast scan, desity of tuberculoma showed largely isiodense (68%), ring-shaped (29%) and target shaped (3%). 5. All rings were continuous and thickness was largely uniform (67%), and density of center of the ring was mainly low (67%). 6. Edema was seen in 58% of all lesions : comparing with the size of tuberculoma, edema size was smaller in 50%, larger in 33% and almost the same in 17%.
