Hypodense collection within the retropharyngeal space, extending from the level of C1, with a maximal depth of 1.4cm at the level of C3. Extension into left prevertebral and paraspinal muscles where multiple loculated, rim-enhancing collections are demonstrated. A 8.3cm low density region is demonstrated at the posterior aspect of nasopharnyx on the left, also likely representing a collection. Anterior displacement of the oesophagus. Airway is patent.
Within the chest, a moderate amount of fluid and stranding is demonstrated within the mediastinum. Non-enlarged mediastinal lymph nodes are noted. Small bilateral pleural effusions and bibasal atelecatsis.
Conclusion: Appearance is consistent with a retropharyngeal abscess with extension into the left perivertebral space and superior mediastinum.
