TB or not TB?

These 3 cases illustrate what we believe to be unusual presentations of tuberculosis. In no case was there conclusive proof of infection with Mycobacterium tuberculosis using histological, microbiological or radiological techniques. All were treated empirically with anti-tuberculous medication, with complete recovery. With the re-emergence of tuberculosis, there may be a rise in such cases, and the importance of their recognition and empirical treatment is discussed.
