A Hidden Timebomb: Unusual Presentation of Retropharyngeal Abscess in Adult

Abstract

Retropharyngeal abscess (RPA) is a deep neck tissue infection. It is an uncommon but potentially life-threatening diagnosis due to its anatomical location. RPA occurs more commonly in children due to the abundance of retropharyngeal lymph nodes. In adults, RPAs are rare and can occur as a result of local trauma, such as foreign body ingestion (fishbone) or instrumental procedures (laryngoscopy, nasogastric tube placement, and endotracheal intubation). We described a case of an unusual presentation of RPA in a morbidly obese adult without a history of local trauma. This report highlights the importance of considering RPA for atypical presentations and the value of lateral neck radiographs in primary settings and emergency departments.
