16. PROFILE OF BRAIN ABSCESSES CONCLUSIONS CONCLUSIONS - We prefer primary excision of abscess in Infratentorial compartment and Aspiration in other regions. - Tuberculosis should be strongly suspected in all cases and searched for.

17. - Hydrocephalus can develop in a number of successfully treated patients(21%in our series), though only a small percentage will require shunt placement. PROFILE OF BRAIN ABSCESSES CONCLUSIONS (Contd.) CONCLUSIONS (Contd.)
