CTICasesTracheal Adenoid Cystic Carcinoma
Imaging findings
Chest radiograph reveals subtle narrowing of the tracheal air column. CT and PET CT confirm a large, lobulated, asymmetric soft-tissue tumor arising from the lateral wall of the trachea, demonstrating marked intraluminal extension and mild FDG avidity.
Key takeaways
Adenoid cystic carcinoma is a primary malignant tumor of the trachea that often occurs in younger patients. Because its clinical presentation mimics asthma or bronchitis, it is frequently diagnosed late. These tumors characteristically grow with extensive submucosal and perineural infiltration, making complete surgical resection challenging.
