 There are post-treatment findings with persistent diffuse pharyngeal mucosal space, retropharyngeal space, and parapharyngeal space edema. Otherwise, there is an infiltrative, enhancing conglomerate of left level 2 lymph nodes measures up to 35 x 55 mm in axial cross-section. The lesions at least partially encase the left internal carotid artery and narrow the left internal jugular vein. In addition, a left level 3 lymph node measures 12 x 14 mm in axial cross-section. Furthermore, there is a nodule within the deep parotid space, which measures 12 x 16 mm. There is no significant lymphadenopathy in the right neck. There is fatty atrophy of the submandibular glands. The thyroid gland is unremarkable. There is mild plaque at the carotid bifurcations. There is multilevel degenerative spondylosis. There is mild sinus mucosal thickening. There are bilateral lens implants. There is patchy T2 hyperintensity in the cerebral white matter, which may represent chronic small vessel ischemic disease.
