Tuberculous meningitis in immunocompetent adults: two cases with a clinico-radiological discussion.

ABSTRACT

In developed countries with a low incidence of tuberculosis, infection with Mycobacterium tuberculosis is easily overlooked as the cause of meningitis in an immunocompetent adult. Two cases are presented, with emphasis on the main reasons for delay of diagnosis. Neuroradiology revealed a progressive hypertrophic basal meningitis. The clinical and radiological outcome was good after tuberculostatic and corticosteroid treatment.
