A retropharyngeal abscess is an abscess in the tissues in the back of the throat, the retropharyngeal space; behind the posterior pharyngeal wall.

It can lead to airway obstruction, a life-threatening emergency.[1] Fatalities normally occur from patients not receiving treatment immediately and suffocating prior to knowing that anything serious was wrong.

Causes

It is usually caused by a bacterial infection originating from the nasopharynx, tonsils, sinuses, adenoids or middle ear. It can also result from a direct infection due to penetrating injury or a foreign body.

Symptoms

Symptoms include difficulty swallowing, fever and enlarged cervical lymph nodes.

Treatment

Retropharyngeal abscesses often need to be drained surgically. A vertical incision is made in the upper neck to drain the pus. Tracheotomy is often required to prevent upper airway obstruction caused by oedema in the neck. Antibiotics are also given.

Diagnosis

X ray of the neck 80% of the time shows swelling of the retropharyngeal space. CT however is the test of choice as it shows abnormality 100% of the time.[2]
