Recurrent nasopharyngeal cancer, EBV+, treated with and radiation therapy 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 no evidence of significant cervical lymphadenopathy based on size criteria. The thyroid and major salivary glands are unchanged. There is cervical spondylosis with at least moderate spinal canal stenosis at C5 and C6 with possible associated high T2 signal in the spinal cord. There are several cervical neural foramina subcentimeter perineural cysts. There are degenerative changes in the right temporomandibular joint with an associated 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. The skull and extracranial soft tissues are otherwise unremarkable.
1. Post-treatment findings in the right nasopharynx without measurable residual mass, although assessment is limited by the lack of intravenous contrast. 2. No evidence of intracranial tumor, although assessment is limited by the lack of intravenous contrast. 3. Degenerative spondylosis of the cervical spine with spinal canal stenosis at C5 and C6 and possible associated myelomalacia, although the sequences are not optimized for assessment of the spinal cord.
