Learning objectives

Our purpose is to provide an educational exhibit illustrating the crucial head and neck anatomy in magnetic resonance imaging (MRI) utilized in the correct local staging of head and neck cancers. The approach is based on anatomic localization, with an emphasis on the anatomy of the nasopharynx, oral cavity, oropharynx, hypopharynx, larynx, nodal levels, deep cervical spaces and utilization of diffusion weighted images (DWI) to identify possible regions of locoregional tumor that need more meticulous characterization and evaluation. This is not designed to be a...

Background

This is a retrospective case review of a broad range of pathologically and clinically proven cases of head and neck neoplasms accumulated from 2000-2012 at a tertiary referral university medical center and from 2010-2012 at a large private practice clinic with MRI service to the local university medical center. These are organized by location of the primary neoplasm and pertinent anatomy for the local staging. High quality anatomical and DWI images are used to illustrate the findings.

Findings and procedure details

Legend:1) BM: Bone marrow; 2) CN: Cranial nerve; 3) EBV: Epstein-Barr virus; 4) IJV: Internal jugular vein; 5) NHL: Non-Hodgkin lymphoma; 6) PPS: Parapharyngeal space; 7) SCM: Sternocleidomastoid muscle; 8) SCC: Squamous cell carcinoma I-DEEP SPACES OF THE NECK HOW TO LOCALIZE A LESION TO THE CORRECT DEEP SPACE: Find the center of the mass and evaluate how it displaces the parapharyngeal space (PPS). For example, a lesion in the carotid space will displace the PPS medially and anteriorly (See Fig. 1). This schema works...

Conclusion

The viewer of this exhibit will gain or refresh information about critical MRI anatomy for the staging of head and neck cancers useful in clinical practice and for preparation for certifying examinations. The images provided aid in recognition of critical anatomical structures that must be thoroughly evaluated and categorized in order to arrive at the correct staging of head and neck cancers. Staging of head and neck can present a diagnostic challenge. Critical anatomy that needs to be recognized and evaluated for the correct staging...
