Extramucosal Spaces of the Head and Neck

The extramucosal head and neck consists of several distinct spaces bounded by fascia [1, 2]. Knowing the anatomy of these spaces and their contents helps the radiologist to describe and correctly diagnose pathology. Some neck diseases are incidental findings while others are large enough to present as a palpable mass. Other diseases are not large, but in a location that leads to symptoms of ear pain, ear pressure/fullness, tinnitus, dysphagia, or cranial nerve palsies.
