An 83-year-old woman complained of pain on the right side of the neck. Nasopharyngeal fiberscopy revealed swelling of the posterior wall from the upper to the lower pharynx. CT scans revealed an abscess on the right side of the retropharyngeal space with infiltration of the right atlas. The abscess was incised, the area was irrigated, and antibiotics were administrated. Retropharyngeal abscess is common in children. In adults, it is often caused by tuberculosis, upper respiratory infections or foreign bodies in the throat. It is necessary to culture for anaerobes and to select antibiotics.
