BRONCHIOLITIS OBLITERANS ORGANIZING PNEUMONIA SIMULATING BRONCHIAL-CARCINOMA

Idiopathic bronchiolitis obliterans organising pneumonia (BOOP) is an uncommon but well-recognised condition that usually presents radiologi cally as bilateral multifocal patchy areas of consolidation on the che st radiograph and on computed tomography (CT). Five cases are describe d in which the presenting feature was that of a solitary pulmonary nod ule. Four of these nodules showed evidence of cavitation and three pat ients presented with haemoptysis. In all cases the appearances closely resembled bronchial carcinoma.
