Extrapulmonary tuberculosis in high prevalence of tuberculosis and low prevalence of HIV.

The authors' data show a higher rate of pleural and meningeal involvement among extrapulmonary TB cases than expected by previous works. Special attention should be given to tuberculous meningitis cases among all extrapulmonary TB cases because of its high mortality rate. The most common extrapulmonary involvement is pleural. Pleural involvement is most common among the young male military service personnel. These data underscore the importance of determining pleural involvement among extrapulmonary TB cases and emphasize the need to consider clinic and epidemiologic differences in the diagnosis and evaluation of extrapulmonary TB. Finally, it seems unlikely that HIV infection currently has a role in the cause of extrapulmonary TB in the authors' region.
