Axial CT scans of thorax obtained at two different levels illustrate proximal
(A) and distal (B) parts of duplicated trachea. Note diameter
difference between main lumen and accessory lumen (arrow).

Fig. 1C. 2-month-old boy with partial duplication of mid trachea.
Volume-rendered images of tracheobronchial tree show anterior (C) and
left posterior oblique (D) projections with and without lung
parenchyma, respectively. Extent and configuration of duplicated mid trachea
are seen better on left posterior oblique image (D). Accessory lumen
(arrows) appears stenotic at mid segment.
