Full Definition
Retropharyngeal abscess is a collection of pus in the retropharyngeal space, most commonly occurring in children under 6 years due to the presence of lymphoid tissue that regresses with age. The condition typically follows upper respiratory tract infection or trauma and presents with fever, neck stiffness, drooling, and difficulty swallowing. Complications include airway obstruction, aspiration pneumonia, and descending necrotizing mediastinitis. Prompt diagnosis and treatment are essential to prevent life-threatening complications.
Usage
Usage note: Potentially life-threatening condition requiring urgent airway assessment and management.
