Imaging of Laryngeal and Hypopharyngeal Squamous Cell Cancers.

This article provides a comprehensive overview of imaging in the evaluation of laryngeal and hypopharyngeal squamous cell carcinomas. It highlights the critical role of computed tomography (CT), MR imaging, and PET/CT in staging, treatment planning, and surveillance. Key anatomic landmarks, patterns of tumor spread, imaging features relevant to TNM staging, and post-treatment changes are discussed. Emphasis is placed on identifying imaging findings that alter management, such as subsite evaluations, cartilage invasion, extralaryngeal extension, and regional nodal metastasis. The article also addresses common diagnostic challenges and pearls for accurate interpretation.
