title: Changing patterns in pulmonary tuberculosis.
abstract: We reviewed the initial chest roentgenograms of 182 consecutive adult patients with proven active tuberculosis. Less than 50% of all cases were known or suspected at the time of initial presentation. There is a low degree of correlation between radiologically discernible active pulmonary tuberculosis and extrapulmonary tuberculosis. A high percentage of cases represent uncommon pulmonary locations. We present the frequency of occurrence of four common pulmonary patterns.
