Intracranial tuberculomas and the CAT scan

Abstract

Tuberculomas of the brain are rare in the United States. Although CAT (computerized axial tomography) scanning cannot distinguish these infections from other intracranial mass lesions, it provides a non-invasive technique with which to follow the course of presumptive lesions during medical therapy, and with which to search for clinically unsuspected infections. The necessity for and timing of surgery can be considered more easily with this technique. Two cases are presented with their CAT scans, including one example of the disappearance of a presumptive tuberculoma, during appropriate medical therapy.
