CTICasesEndobronchial Metastasis from Oral Squamous Cell Carcinoma
Imaging findings
Chest CT demonstrates extensive peribronchial thickening and multiple soft tissue masses directly filling the lumens of several lobar and segmental bronchi, with associated bronchovascular bundle thickening.
Key takeaways
Endobronchial metastasis is a rare manifestation of extrapulmonary malignancies, with renal cell carcinoma, melanoma, and breast cancer being the most common culprits. Squamous cell carcinoma of the oral cavity can also spread to the airways, presenting with symptoms of airway obstruction or mimicking primary bronchogenic carcinoma.
