Nine cases of brain abscess, five of subdural empyema, and one of epidural empyema with associated subdural empyema were identified using computed tomography (CT). Smal and multiple abscesses as well as unilateral, bilateral, and parafalcine empyemas were detected. ⋯ No false-negative studies were found in cases of brain abscess or subdural empyema. However, since the appearance of brain abscesses of CT scans is similar to that of neoplastic and vascular lesions, false-positive reports of brain abscess were encountered.
