  • Title: Value of the ring-enhancing sign in differentiating intracerebral hematomas and brain abscesses.
    Author: Salzman C, Tuazon CU.
    Journal: Arch Intern Med; 1987 May; 147(5):951-2. PubMed ID: 3579448.
    Abstract:
    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.
