[Diagnostic imaging of current pulmonary tuberculosis. Clinical significance of the presentation patterns and particular aspects in HIV-positive and HIV-negative subjects].
OBJECTIVE
We compared two groups of risk patients to try to identify different radiologic patterns in pulmonary tuberculosis.


METHODS
74 subjects, divided into two groups (HIV+:27; HIV-:47) were included since 1993. The patients were examined with chest X-ray (CXR) and CT.


RESULTS
In the HIV+ group we observed 40 radiologic alterations, with 6 cases of bilateral lung involvement and 9 of atypical localizations; particularly: 11 consolidations, 8 cavitations, 5 miliary diseases, 9 hilar or mediastinal adenopathies, 3 extrapulmonary localizations and 4 negative CXRs. In the HIV- group we found 53 radiologic alterations, with 6 cases of bilateral lung involvement and 3 of atypical localizations; particularly: 12 consolidations, 25 cavitations, 5 nodular patterns, 1 miliary disease, 5 nodal disease, 4 pleural diseases and 1 negative CRX.


CONCLUSIONS
In HIV- patients lung consolidations and tysiogen patterns are significantly prevalent, while miliary diseases, mediastinal diseases and atypical localizations and negative CRXs are more frequent in HIV+ patients. We found miliary diseases, mediastinal diseases and extrapulmonary localizations also in HIV- patients with heavily impaired social, economic and sanitary conditions. This alterations indicate compromised host resistance, independent of the causes and modalities of immunodeficiency. The distinction between primary and secondary tuberculosis is currently not mandatory.
