Retropharyngeal Abscess: Patterns of Deep Neck Space Extension and Clinical Findings From 11 Adult Cases

Adult RPA frequently presents with extensive spread beyond the retropharyngeal space, owing to the anatomical continuity of this compartment, which facilitates rapid extension to the parapharyngeal, prevertebral, and mediastinal regions. Contrast-enhanced CT is essential for defining disease extent. Prompt airway evaluation and early broad-spectrum antibiotic therapy combined with surgical drainage remains the cornerstone of management, contributing to favorable outcomes.
