Figure 1. (a) CT of a 28-year-old woman with bronchioloalveolar carcinoma shows consolidation occupying the entire right hemithorax. Right upper lobe bronchus shows widening of the angle and sweeping (black arrows). The bronchus is also diffusely narrowed (squeezing). Metastases in the left upper lobe show as rounded nodules of variable size (white arrows). (b) The lower portion of the mass shows low attenuating consolidation with the CT angiogram sign. There is diffuse marginal enhancement of the tumour (arrows).

Figure 3. CT of a 65-year-old man with mucinous bronchioloalveolar carcinoma shows diffuse ground-glass opacities and consolidation. Note the associated thickened interlobular septa producing a "crazy paving" pattern. The bronchus in the involved lesion is stretched and squeezed (arrows).
