Reformatted coronal CT MIP image in soft tissue window-level setting (a) demonstrates presence of a hyperdense foreign body (solid arrow) within a thickened left mainstem bronchus (arrowheads). Also noted is subcarinal (block arrow) and hilar adenopathy which was later shown to represent nodal metastasis from lung adenocarcinoma. Axial CT imaging in lung window-level setting (b) shows resultant hyperinflation and hyperlucency of the left upper lobe related to air-trapping.
