Abstract:
Primary adenoid cystic carcinoma in the trachea is a very rare tumor. A 40-year-old woman presented with persisting cough and wheezing over 2 months. A CT scan showed a mass in the tracheal wall. The bronchoscopic biopsy confirmed adenoid cystic carcinoma. 18F-FDG PET/CT was performed to evaluate the tracheal mass, which showed an FDG-avid mass in the right posterior tracheal wall.
