Right nasopharyngeal carcinoma, treated with and radiation and chemotherapy. Neck: There are post-treatment findings in the right nasopharynx with mild right asymmetric pharyngeal mucosal space thickening without measurable residual mass, although assessment is limited by the lack of intravenous contrast. There is also diffuse mucosal enhancement that is suggestive of mucositis. There is no evidence of significant cervical lymphadenopathy based on size criteria. The thyroid and major salivary glands are unchanged. There is unchanged enhancement within the right mandibular ramus. There is mild anterolisthesis of C3 on C4 and C4 on C5, as well as cervical spondylosis with at least moderate spinal canal stenosis at C5 and C6 and retrolisthesis of C6 on C7. There are several cervical neural foramina subcentimeter perineural cysts. There are degenerative changes in the right temporomandibular joint with an associated trace effusion.Brain: There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is mild nonspecific cerebral white matter T2 hyperintensity. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. There is persistent fluid signal within the bilateral mastoid air cells. There are maxillary sinus retention cysts and scattered paranasal sinus mucosal thickening. There is radiation-associated fatty marrow signal in the skull base and upper cervical spine.
