CTICasesPrimary Tracheal Squamous Cell Carcinoma
Imaging findings
CT of the neck and chest reveals a severe, circumferential, and exophytic soft tissue thickening narrowing the tracheal lumen. Over time, follow-up CT and PET/CT imaging demonstrate significant progression of the hypermetabolic mass, causing critical luminal narrowing.
Key takeaways
Although primary tracheal tumors in young, non-smoking females are classically expected to be adenoid cystic carcinoma, primary squamous cell carcinoma can occur and may present as a narrowing, exophytic, and infiltrative mass rather than a purely mucosal-eroding lesion. This case underscores the importance of not dismissing tracheal thickening as post-traumatic or benign and ensuring rigorous follow-up.
