Retropharyngeal abscess is a collection of pus in the tissues in the back of the throat. It can be a life-threatening medical condition.
Retropharyngeal abscess most often affects children under age 5, but it can occur at any age.
Infected material (pus) builds up in the space around the tissues at the back of the throat. This can occur during or very soon after a throat infection.
Exams and Tests
The health care provider will perform a physical exam and look inside the throat. The provider may gently rub the back of the throat with a cotton swab. This is to take a sample of tissue to check it more closely. It is called a throat culture.
Other tests may include:
Surgery is needed to drain the infected area. Corticosteroids are sometimes given to reduce airway swelling. High-dose antibiotics are given through a vein (intravenous) to treat the infection.
The airway will be protected so that it does not become completely blocked by the swelling.
It is important to get medical help right away. This condition can lead to blockage of the airway. This is life threatening. With prompt treatment, a full recovery is expected.
Complications may include:
