Sabre-sheath Trachea

CXR: Shortness of breath. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ CXR: Hyperinflated lungs, tracheal narrowing in the coronal plane at the level of the aortic arch. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ CT: "Sabre-sheath" trachea and moderate to severe centrilobular emphysema. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ This is an example of a "sabre-sheath" trachea with narrowing of the trachea in the coronal plane and preservation/widening in the sagittal plane. A sabre-sheath trachea is pathognomonic for COPD: this is a good example with concomitant moderate/severe centrilobular emphysema. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ 👤Case courtesy of Stefan Tigges, Radiopaedia.org, rID: 98152
