Imaging Anatomy of the Infrahyoid Neck

Area of Science:

• Anatomy
• Radiology
• Surgical Pathology

Background:

• The infrahyoid neck spaces are defined by deep cervical fascia layers.
• Understanding these spaces is crucial for accurate diagnosis and effective management.

Purpose of the Study:

• To explore the anatomy and imaging characteristics of infrahyoid neck spaces.
• To present a space-based approach for differential diagnosis and clinical decision-making.
• To discuss anatomic variants and mediastinal connections for disease spread and treatment planning.

Main Methods:

• Review of anatomical literature and imaging studies.
• Analysis of imaging characteristics, contents, and relationships of infrahyoid neck spaces.
• Discussion of common anatomic variants and pathways to the superior mediastinum.

Main Results:

• Detailed description of infrahyoid neck space anatomy and imaging features.
• A systematic, space-based approach to differential diagnosis is proposed.
• Clinical relevance of anatomic variants and mediastinal connections is highlighted.

Conclusions:

• A comprehensive understanding of infrahyoid neck spaces is essential for clinicians.
• The space-based approach aids in accurate diagnosis, error avoidance, and surgical planning.
• Knowledge of mediastinal pathways is critical for managing disease spread.
