title: Tuberculous brain abscess and subdural empyema in an immunocompetent child: Significance of AFB staining in aspirated pus.
abstract: Tuberculous brain abscess and subdural empyema are extremely rare manifestations of central nervous system tuberculosis. Here, we report a case of an 11-year-old immunocompetent child who developed temporal lobe abscess and subdural empyema following chronic otitis media. A right temporal craniotomy was performed and the abscess was excised. The Ziehl Nielsen staining of the aspirated pus from the temporal lobe abscess yielded acid fast bacilli. Prompt administration of antituberculous treatment resulted in complete recovery of the child. Even though the subdural abscess was not drained, we presume that to be of tubercular aetiology. Ours is probably the first case of brain abscess and subdural empyema due to Mycobacterium tuberculosis reported in the same child. This case is being reported because of its rarity and to stress the importance of routine staining for tubercle bacilli in all cases of brain abscess, especially in endemic areas, as it is difficult to differentiate tuberculous from pyogenic abscess clinically as well as histopathologically.
