Clinical and roentgenographic spectrum of pulmonary tuberculosis in the adult.

In order to define the roentgenographic manifestations of pulmonary tuberculosis in the adult, we reviewed a 12 month experience with newly diagnosed patients with active pulmonary tuberculosis in two Boston hospitals. Of 88 patients, 30 (34 per cent) presented with roentgenographic manifestations other than those associated with "usual" postprimary disease. At least 12 patients (13.5 per cent) had primary tuberculosis, including two subjects over 60 years of age. Six patients (6.8 per cent) had disease confined to the lower lung fields, eight patients (9 per cent) had tuberculomas and four (4.5 per cent) had miliary tuberculosis. Twenty per cent of the patients were totally asymptomatic. With the shift of tuberculosis care to community hospitals, knowledge of the varied roentgenographic manifestations is of increasing importance for the practicing internist.
