Fig 1.
Squamous cell carcinoma of the lower trachea and involvement of right main bronchus.
MDCT axial image (A), MPR (coronal, B; sagittal, C), VR (D) and VB (E) images disclosed a wide based and irregular tumor, protruded into endolumen with severe eccentric lumenial stenosis, still homogeneous density and fairly obvious enhancement, extending to right main bronchus, and longitudinal involvement of 53.7 mm.

Comparison between detection results with MDCT and its MPR, VR and VB and surgical and pathological results of 31 primary trachea and main bronchus tumors.
Fig 2.
MDCT axial image (A), MPR (oblique, B) and VB (C) images revealed around and polypiform mass, and protruded into endolumen with a narrow peduncle connected to wall, not thickened wall, severe eccentric lumenial stenosis, and homogeneous density without obvious enhancement.
