Methods：CT features of 22 patients with pathologically or clinically proved were retrospectively analyzed. All cases were performed both non-enhance and enhance scan. Results：Among 22 cases, there were 17 brain abscess that distribute in the hemisphere, while cerebellar hemisphere 3 cases, basal region and thalamus 1 case, respectively. The abscess wall of 18 patients were integrity, while 3 cases showed the imperfect ring. Conclusion：The position, size, thickness and morphology ofabscess wall are clearly demonstrated on the spiral CT, which are helpful for the differential diagnosis of solitary ring-enhanced lesions.
