Fig. 1A. 34-year-old man who underwent lung transplantation for silicosis and
developed right lower lobe consolidation 3 days later. Axial helical CT scan
obtained at level of bronchus intermedius reveals posterolateral displacement
of right middle lobe bronchus (black arrow). Note narrowing of lower
lobe bronchus (arrowhead). Also note prominent interlobular septal
thickening in displaced right middle lobe (white arrow).

Fig. 1B. 34-year-old man who underwent lung transplantation for silicosis and
developed right lower lobe consolidation 3 days later. Axial helical CT scan
with mediastinal window settings shows abnormal transposition of lower lobe
pulmonary artery (long arrow) relative to narrowed inferior pulmonary
vein (short arrow).

Fig. 1C. 34-year-old man who underwent lung transplantation for silicosis and
developed right lower lobe consolidation 3 days later. Axial helical CT scan
inferior to A shows posterolateral displacement of right middle lobe
(M). Consolidated right lower lobe (L) is anteromedially displaced. Posterior
consolidation (arrow) is probably caused by venous congestion and
infarction.

Fig. 1D. 34-year-old man who underwent lung transplantation for silicosis and
developed right lower lobe consolidation 3 days later. Sagittal multiplanar
reconstruction shows abnormally reversed orientation of right major fissure
(straight arrows). Note inferiorly displaced and congested superior
segment of right lower lobe (curved arrow). A = anterior, P =
posterior.

Fig. 1E. 34-year-old man who underwent lung transplantation for silicosis and
developed right lower lobe consolidation 3 days later. Bronchoscopic image
(oriented to look down from head of patient) obtained at level of bronchus
intermedius shows abnormal orientation of right middle lobe bronchus (M)
(long arrow). Note expected location of right middle lobe orifice
(short arrow). Lower lobe bronchus (L) is narrowed and erythematous.
Bronchoscopic orientation: a = anterior, p = posterior, m = medial, l =
lateral.
