Tubercular brain abscess (TBA) is a rare manifestation of CNS tuberculosis. We report a case of
tuberculous brain abscess in an adolescent girl who developed unilateral proptosis while on
treatment of abdominal tuberculosis. Her diagnosis was confirmed on staining of pus that was
drained and she improved after surgical drainage of abscess. Ziehl-Neelsen and immunofluorescence
staining of pus /fluid are simple and quick techniques to confirm diagnosis.
