The prevertebral muscles
and the cervical vertebrae were normal.
(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. (12,13)
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).
* adjacency to the physiologic FDG-avid prevertebral muscle.
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
. The buccopharyngeal fascia covers the side and the back of the pharynx.The prevertebral fascia is firmly attached at the midline of the back of the pharynx.
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
. It is delimited medially by the pharyngobasilar fascia and the superior pharyngeal constrictor muscle, and laterally by the ascending branch of the jaw, superficial cervical aponeurosis and the submaxillary gland.
There is some anterior displacement of the posterior wall of the pharynx from the prevertebral muscles
. However, the symmetric displacement does not exceed more than a few millimeters.
Calcific tendinitis of the prevertebral muscles
is a rare clinical entity.
