Three layers of DCF Anatomy of the head and neck
Spatial approach
 Deep Cervical Fascia 3 layers
 These layers define ´spaces´
 Spaces are oriented in the axial plane
Anatomy of the head and neck
Spatial approach
 Deep Cervical Fascia 3 layers
 These layers define ´spaces´
 Spaces are oriented in the axial plane
 Useful for analyzing axial cross-sectional
images (CT / MRI)
Spaces defined by DCF
 Parapharyngeal = Prestyloid PPS *
 Pharyngeal mucosal
 Masticator
 Parotid
 Carotid = Poststyloid PPS *
 Retropharyngeal / Danger
 Perivertebral

Clinical suspicion of head & neck mass
What is expected of the radiologist?
 Correct identification of space of origin
– normal spatial anatomy
– radiographic pattern recognition
– integration of clinical information
 Limited space-specific DD
Clinical suspicion of head & neck mass
What is expected of the radiologist?
 Correct identification of space of origin

– 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)
