Although visually remarkable, this finding is of no practical clinical significance. However, tracheal calcification may occur more often among patients who have taken an anticoagulation medication, such as warfarin sodium, for several years.1 Although the mechanism by which warfarin causes tracheal calcification is unknown, it may inhibit the normal formation of a vitamin K–dependent protein that prevents calcification of cartilage and connective tissue.2
