[Thoracic tuberculosis in adults. A comparative study of radiological findings of HIV seropositive and seronegative patients].

We compare the radiologic manifestations of chest TB in three groups of patients: HIV patients (52 cases), HIV negative patients (85 cases and 100 cases). Initial radiologic findings were similar in the two seronegative groups, even though there is an eight-year interval between both series. However, seropositive patients have a higher risk of acquiring the infection (x 2.25), of extrathoracic disease (x 4.22), of coincidental infections (p < 0.0002) and of progression of the disease p < 0.0003) than the normal population. Lymphadenopathy and miliary TB are much more common in the HIV positive patients (x 6.23 and x 44 respectively). Cavitation, pulmonary scarring, volume loss and calcification are more frequent among the seronegative patients (p < 0.03), as well as pleural disease (p < 0.0001).
