Tuberculous brain abscess in an immunocompetent adolescent.

Tuberculous brain abscess (TBA) is one of the rare forms of central nervous system tuberculosis. A case of tuberculous cerebellar abscess in a young immunocompetent adult male is being described. There was no clinical or radiological evidence of active tuberculosis elsewhere in the body. The diagnosis of tubercular abscess was confirmed by demonstration of acid fast bacilli in the abscess material aspirated via a burr hole. High index of suspicion and timely intervention is required to diagnose and treat this potential fatal but easily treatable condition.
