Background
Imaging is an essential component for evaluation of submucosal tumors of the larynx and trachea, to narrow the differential diagnosis, guide sampling, and assess the integrity of the laryngeal cartilage and extent of the process for treatment planning. This exhibit reviews the uncommon benign and malignant non-epithelial masses of the larynx and trachea, infectious, inflammatory, and other processes that may mimic masses.
Educational Goals / Teaching Points
After reviewing this exhibit, participants will be able to recognize submucosal processes in the larynx and trachea, describe extent of involvement related to key anatomic structures, and refine differential diagnosis based on imaging findings and demographics.
Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Imaging findings to support diagnosis and guide sampling, and features which impact treatment planning are addressed through example cases including granulomatous polyangiitis, tuberculosis, papilloma, amyloid, nerve sheath tumor, lymphatic malformation, granular cell tumor, minor salivary tumor, chondrosarcomam, and myeloid sarcomam.
Conclusion
Imaging plays a key role in diagnosis and evaluation of submucosal laryngeal and tracheal masses. Imaging findings of margin assessment related to key anatomy are essential for treatment planning and symptom surveillance.
