A 40-year-old female presented to the emergency department with a one-week history of URI symptoms and a one-day history of more severe throat pain and swelling. Upon physical examination the patient was afebrile and although she did not demonstrate any signs of respiratory distress, examination of her neck revealed fullness on the right. A lateral plain film of the neck showed soft tissue swelling anterior to the vertebral bodies (Figure 1) and a CT scan demonstrated fluid in the retropharyngeal space and an abscess. Fiberoptic laryngoscopy was performed and the airway was found to be swollen and compromised. The patient was taken to the operating room for an awake tracheostomy, the abscess was incised and drained, and she was admitted for overnight observation.
Despite the advent of antibiotics and improvement of dental hygiene, deep space neck infections persist as a cause of morbidity and mortality. Retropharyngeal abscess (RPA) is an ENT emergency due to the possibility of life-threatening airway complications.1Patients with RPA typically have localized symptoms of dysphagia, voice changes, odynophagia, trismus, and neck/jaw pain.2 Generalized symptoms of fever, chills, and loss of appetite may be present as well. Indicators of RP abscess during the physical exam are stridor, shortness of breath, drooling, cervical lymphadenopathy, and bulging of the pharyngeal wall.3 Lateral radiographs will manifest with preveterbral air/fluid levels or abnormal widening of the prevertebral soft tissue, normally 5 – 7 mm wide at the level of the second cervical vertebrae.2 Treatment in the Emergency Department should focus primarily on ensuring a patent airway. Oral intubation may be compromised by a large abscess or in turn may lead to rupture of the abscess, so ENT should be consulted for emergency tracheostomy. Antibiotic choices include high-dose penicillin plus metronidazole, piperacillin/tazobactam, ampicillin/sulbactam or ticarcillin/clavulanate.2
