Findings:

CT csan of neck with pre- and post- intravenous contrast, and
 with multiplanar reconstruction:

1. Marked swelling of right parotid gland with extensive lobulated
   fluid accumulation (red arrow in figure 3 and 4), compatible with
   infectious process with abscess. Presence of derect extension of
   the fluid into adjacent right parapharyngeal, retropharyngeal, and
   paraspinal portion of right perivertebral spaces.
   Besides, the lesion also extension into right posterior cheek
   soft tissue and along right lateral neck into supraclavian fossa.
2. Presence of mass effect of the above lesion with compression
   of larynx causing airway moderate stenosis (yellow arrow in figure
   3 and 4). Please check it!
3. Swelling of left parotid gland with multiple cystic foci
   and derect extension into adjacent paraspinal portion of
   left perivertebral space also.
4. Peribronchial infiltration in both lungs with two nodules in
   both lungs (green arrows in figure 5) and a cavity lesion in right
   upper lung (blue arrow in figure 5), infectious process such as
   septic emboli can not be excluded.

Impression:
1. Infectious process in bilateral parotid glands, predominant over
   right side, with abscess formation and airway compression.
2. Suspicious septic emboli, both lungs.
