Abstract
Data are presented from thirteen patients with marked coronal narrowing of the intrathoracic trachea associated with widening of the corresponding sagittal diameter. The term "saber-sheath" trachea describes this deformity which can simulate a mediastinal mass. The absence of mediastinal masses and the presence of obstructive pulmonary abnormalities in each patient, either as a clinical diagnosis (11 of 13), functional abnormality (10 of 11) or both (8 of 11), suggest that the "saber-sheath" trachea may be a useful sign of chronic obstructive pulmonary disease.Keywords
