Retropharyngeal abscess

Definition:

A collection of pus in the tissues in the back of the throat. See also Peritonsillar abscess.

Causes, incidence, and risk factors:

Retropharyngeal abscess is a disease of children generally under age 5 years. Tissues at the back of the throat in young children allow for the formation of a pus-filled space (which doesn't occur in adults) immediately behind the back of the throat. This area can become secondarily infected during or immediately following a bacterial sore throat.

The affected child, who may still have symptoms of the original sore throat, develops a high fever with an extremely severe sore throat. The pain causes difficulty swallowing and the expanding abscess may interfere with breathing. Complications can be life threatening.

Retropharyngeal abscess requires immediate attention to prevent severe complications.
