Computerized tomography (CT) is a sensitive method for detecting intracerebral pathology. Ring enhancement on contrast CT scan is a classic finding for intracerebral abscesses. Two cases are described in which clinical and physical findings were not suggestive of brain abscess; however, CT scan disclosed ring-enhancing lesions. Both patients were found to have vascular abnormalities without evidence of infection. The diagnostic dilemmas and specificity of ring enhancement on contrast CT scan are discussed.
