Pulmonary Mycobacterium kansasii infection: comparison of radiological appearances with pulmonary tuberculosis.

Abstract

Differences are seen in the radiographic appearances of pulmonary infection caused by M kansasii and M tuberculosis. These differences are not sufficient to allow a positive diagnosis on the basis of radiographic findings alone, but the presence of a pleural effusion or lower lobe involvement makes M kansasii infection very unlikely.
