Chronic diffuse infiltrative lung disease: determination of the diagnostic value of clinical data, chest radiography, and CT and Bayesian analysis.

abstract：:Pulmonary tuberculosis has long been associated with the formation of cavities in the lung. Many reports in the literature indicate that the occurrence of air-fluid levels in tuberculosis is unusual. The authors present 18 cases of proved active cavitary tuberculosis where air-fluid levels occurred during the active p...
