1) The anatomic components of the PVS in the suprahyoid neck include the following: Prevertebral muscles
(longus colli capitus), vertebral body, cervical disk, spinal canal, vertebral artery and phrenic nerve (Figure 5A).
The lateral type is located lateral to the pharyngeal constrictor muscles, medial to the internal carotid artery, and anterior to the prevertebral muscles.
The medial type is located near the midline directly anterior to the prevertebral muscles.
Of the 26 nodes with a discordant finding, 25 were negative on PET/CT but positive on enhanced CT; they included 13 nodes with low FDG uptake, 9 close to the primary tumor (figure 1), 2 confluent RLNs and 1 adjacent to physiologic FDG-avid prevertebral muscle (table 3).
The prevertebral fascia separates the visceral compartment of the neck containing the pharynx, trachea, larynx and the thyroid gland from the cervical vertebrae and the prevertebral muscles
We present a case of migrating metallic foreign body embedded into the prevertebral muscles of the neck and share our experience with relevant review of literature.
A radiopaque linear metallic foreign body was seen in the retropharyngeal space embedded into the prevertebral muscles at the level of the 3rd to 5th cervical vertebrae (Fig.
The back wall is delineated by the aponeurosis and the C1, C2 and C3 prevertebral muscles
A retropharyngeal abscess is identified by a low-attenuation fluid collection that causes substantial anterior displacement of the posterior wall of the pharynx from the prevertebral muscles
Calcific tendinitis of the prevertebral muscles
is a rare clinical entity.
