There was no cyanosis and a repeat chest X-ray showed a hyperinflated right lung field with left upper lobe collapse and left mediastinal shift (Figure 1).
Chest CT scan showing collapse consolidation of upper left lobe with prominent air bronchograms (arrow). Note compensatory hyperinflation of the right upper lobe with shift of the mediastinum to the ipsilateral side.

The cardiothoracic surgical unit (CTSU) was involved in the management and a requested chest CT scan showed collapse consolidation of the left upper lobe with extensive air bronchogram and compensatory hyperinflation of the right upper lobe (Figure 2).
(a) Follicular bronchiolitis: hyperplastic lymphoid follicles with pale germinal centres (arrows) adjacent to a small bronchi and bronchioles (H&E x40). (b) Organizing pneumonia: plugs of granulation tissue (Masson bodies) (arrows) within the alveolar ducts and spaces (H&E x100).

Some of the bronchioles contained inflammatory debris, and plugs of granulation tissue composed of fibroblasts within a myxoid stroma were seen within the bronchiolar lumens, alveolar ducts, and associated alveolar spaces (Figure 3).
