As noted previously, to rule-out the diagnosis of active TB
requires serial sputa examinations as well as the use of chest
radiographs. However, in the HIV + population, the ruling out of TB may be more difficult as the chest x-ray may lack the characteristic upper lobe infiltrate(s) or cavitary lesions. As well, the clinical presentation may be more subtle in presentation. Additionally, the simultaneous occurrence of other pulmonary pathogens may obscure the clinical picture (e.g. the positive AFB smear subsequently yields
Mycobacterium avium-intracellulare on AFB culture). Thus, one must always consider the possibility of TB in the HIV + population in
order to avoid delayed diagnosis or exposure to others.
