[Retropharyngeal phlegmon in adults. Report of a case and literature review]. / Flemón retrofaríngeo en adultos. Presentación de un caso y revisión de la literatura.

Retropharyngeal phlegmons and abscesses in the adult are uncommon nowdays. We report the case of a 48 years old male diagnosed as retropharyngeal phlegmon of idiopatic cause because no reasons were able to justify the clinical symptoms. Cervical CT was negative for purulent collection and the patient was treated by endovenous antibiotics and steroids until the resolution of his process. The final hospital stay was 12 days and after 10 years follow-up he has not been readmitted due to that pathology.
