Tracheal calcification, or tracheobronchial calcification, is a benign radiological finding of the middle aged and elderly and is usually of no clinical significance.
On this page:
Clinical presentation
Patients are generally asymptomatic.
Pathology
Long-term warfarin therapy may be associated with tracheal calcification, possibly because warfarin prevents the formation of vitamin K-dependent proteins which are responsible for preventing calcification 1,2.
Radiographic features
The appearance is often striking on plain radiograph as individual tracheal rings become radiopaque and stand out from the soft tissue mediastinum.
Treatment and prognosis
No management is necessary.
