An enlarged lymph node within the left-sided retropharyngeal space is of low density indicating suppuration. There is extensive oedema/inflammatory change present within the retropharyngeal space extending from the level of the clivus to the C7/T1 junction, consistent with retropharyngeal phlegmon without mature abscess formation. This produces mass effect on the adjacent pharynx. The airway remains patent. There is no epiglottic oedema. Enlarged lymph nodes throughout neck bilaterally. Visible lung fields are normal.
