Organising pneumonia, also known as bronchiolitis obliterans organising pneumonia (BOOP)-like reaction, has been reported most frequently in association with methotrexate, cyclophosphamide, gold, nitrofurantoin, amiodarone, bleomycin and busulphan (Cleverley et al, 2002; Erasmus et al, 2002) . The chest radiograph shows patchy bilateral areas of consolidation, masses or nodules, which may be symmetric or asymmetric (Müller et al, 1990; Ellis et al, 2000) . In a few patients, the disease manifests with a lone mass. On HRCT, areas of consolidation often have a predominantly peripheral or peribronchial distribution (Müller et al, 1990; Ellis et al, 2000) ( Figure 1C ).
