If the retropharyngeal space is more than half of the size of the C2 vertebra, it may indicate retropharyngeal abscess.
12.
X-ray of the neck often ( 80 % of the time ) shows swelling of the retropharyngeal space in affected individuals.
13.
The investigation of choice is imaging of retropharyngeal space with magnetic resonance imaging ( MRI ), specifically looking for tumour or infection.
14.
The condition often follows soft tissue inflammation in the neck such as in cases of upper respiratory tract infections, peritonsillar or retropharyngeal abscesses.
15.
The carcinoma of tonsil usually spreads through the cervical lymph node levels II, III, IV, V, and retropharyngeal lymph nodes.
16.
This is attached to the prevertebral layer by loose connective tissue only, and thus an easily distended space, the retropharyngeal space, is found between them.
17.
Radiographic examination of the area will show an opaque fluid line in the pouch and if a retropharyngeal lymph node is involved, it may reveal a mass.
18.
Complications may also be severe and long-lasting or permanent, such as vocal cord damage, esophageal perforation and retropharyngeal abscess, bronchial intubation, or nerve injury.
19.
It does not include removal of the suboccipital nodes, periparotid nodes except for infraparotid nodes located in the posterior aspect of the submandibular triangle, buccal nodes, retropharyngeal nodes, or paratracheal nodes . 4
20.
Confirmatory testing for scrapie can only be achieved by applying immunohistochemistry of disease-associated prion protein ( PrP SC ) to tissues collected " post mortem ", including obex ( a brainstem structure ), retropharyngeal lymph node and palatine tonsil.
