Tumors and tumorlike conditions of the large airways.

OBJECTIVE

Large-airway tumors and tumorlike conditions are uncommon, but a systematic approach aids in narrowing the differential diagnosis. In this article, we describe an approach to dealing with large-airway lesions and discuss their imaging characteristics and clinical presentations.

CONCLUSION

We have found it useful to separate these entities into groups on the basis of the distribution pattern (focal vs diffuse) and location (trachea vs bronchi).
