title: TB or not TB: cavitary bronchiolitis obliterans organizing pneumonia mimicking pulmonary tuberculosis.
abstract: Two patients with subacute symptoms and signs compatible with pulmonary tuberculosis (TB) had right upper lobe cavitary infiltrates shown on chest radiography. In both patients, purified protein derivative and microbiologic testing excluded TB, and tissue examination yielded typical histologic changes of bronchiolitis obliterans organizing pneumonia (BOOP). Glucocorticoid therapy led to clinical and radiologic resolution. Though probably rare in this situation, BOOP should be considered in the differential diagnosis of patients presenting with clinical and radiologic features of pulmonary TB.
