CT appearance of lunate trachea.


Journal Article

Computed tomography provides excellent visualization of the trachea, but there have been only limited descriptions of variations in tracheal shape. The normal tracheal cartilage is U shaped. Lunate shaped trachea is uncommon and is characterized by a coronal/sagittal diameter ratio (tracheal index) greater than 1. We present the CT appearance of a lunate shaped trachea with corresponding pathologic sections. Destruction of the membranous septum caused marked increase in the tracheal index in this patient.
