BRONCHIOLITIS OBLITERANS ORGANIZING PNEUMONIA - AN UNUSUAL CAUSE OF SOLITARY PULMONARY NODULE

Bronchiolitis obliterans organizing pneumonia (BOOP) is a pulmonary di sorder with a wide spectrum of radiologic features. Usually, these are bilateral, patchy, alveolar, or ground-glass infiltrates, but other p resentations have also been described. We present a case in which the radiologic appearance was a cavitated pulmonary solitary nodule. We th ink that this finding may justify the inclusion of BOOP in the differe ntial diagnosis of the pulmonary solitary nodule.
