Anatomy of the head and neck Spatial approach

Three layers of DCF

 Deep Cervical Fascia 3 layers  These layers define ´spaces´  Spaces are oriented in the axial plane

Anatomy of the head and neck Spatial approach

Spaces defined by DCF

 Parapharyngeal = Prestyloid PPS *  Pharyngeal mucosal  Masticator

 Deep Cervical Fascia 3 layers  These layers define ´spaces´

 Parotid  Carotid

 Spaces are oriented in the axial plane  Useful for analyzing axial cross-sectional images (CT / MRI)

= Poststyloid PPS *

 Retropharyngeal / Danger  Perivertebral

Clinical suspicion of head & neck mass

Clinical suspicion of head & neck mass

What is expected of the radiologist?

What is expected of the radiologist?

 Correct identification of space of origin – normal spatial anatomy

 Correct identification of space of origin – normal spatial anatomy

– radiographic pattern recognition – integration of clinical information  Limited space-specific DD

– radiographic pattern recognition – integration of clinical information  Limited space-specific DD

 Bottom-line: If you know the spaces, you don’t have to know the 3 layers of DCF (in detail)
