Blastomycosis of the lung: CT features.
The authors reviewed the computed tomographic (CT) scans in 16 patients with pulmonary blastomycosis to describe the abnormalities seen at CT. The CT features were as follows: mass lesions (n = 14), consolidation (n = 9), air bronchograms (n = 14), intermediate-sized nodules (n = 12), satellite lesions (n = 11), pleural thickening (n = 4), small effusions (n = 2), and cavitation (n = 2). One patient had noncalcified hilar lymphadenopathy. Eight patients had acute disease, six had chronic disease, and two had acute exacerbation of a chronic illness. Fifteen patients had cough, fever, and/or dyspnea. Two patients underwent surgical resection for the presumptive diagnosis of bronchogenic carcinoma. In general, there was no correlation between the radiologic abnormalities and the clinical presentation. Consolidation occurred more frequently in acute disease. CT may be useful to help define the radiologic findings and distribution of disease. Familiarity with the characteristic CT findings of pulmonary blastomycosis may encourage an expeditious diagnostic approach to identify the disease and, possibly, prevent unnecessary surgical resection.
