Intracranial tuberculosis: manifestations on computerized tomography

Intracranial tuberculosis is often insidious, may be difficult to diagnose clinically, and is neurologically devastating if untreated. The advent of computerized tomography has permitted earlier detection of the structural abnormalities associated with intracranial tuberculosis than was possible with older techniques. Correct radiologic interpretation can heighten the index of suspicion for what is often an overlooked diagnosis and can lead to earlier treatment, with decreased morbidity and mortality. We present four cases that cover the spectrum of abnormalities of intracranial tuberculosis shown by CT.
