Impression of an indistinct lobulated soft tissue mass measuring approximately 22 x 13 x 26 mm lying within the right posterolateral aspect of the hypopharynx.
There is complete obliteration of the aerodigestive tract at the level of the thyroid cartilage and persistent left-sided deviation of the trachea due to asymmetrical soft tissue thickening on the right side. No definite destruction of the hyoid bone, thyroid or cricoid cartilage.
No associated peripherally enhancing collections within the asymmetrical soft tissue thickening. Presence of enlarged cervical lymph nodes measuring up to 10 mm in short axis with no intrinsic calcifications or central necrosis. Further prominent subcentimetre lymph nodes were seen within the superior mediastinum with fat stranding.
Normal appearance of the parotid and thyroid glands. Incidental large cystic spaces within the right middle cranial fossa measuring 28 x 40 mm with associated displacement of the right MCA branches. This could potentially represent an arachnoid cyst.
