Nasopharyngeal carcinoma status post treatment. Brain: There is no measurable nasopharyngeal tumor. There is persistent diffuse enhancement in the central skull base and pterygopalatine fossae, which is likely treatment related. There are effusions within the bilateral mastoid air cells. There is no evidence of tumor in the cavernous sinuses. There is pansinus mucosal thickening and there are scattered secretions. There are unchanged mild scattered cerebral white matter T2 hyperintense lesions. There is no abnormal intraparenchymal enhancement. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. There is no evidence of acute infarction.Orbits: The bilateral orbits are intact, without evidence of tumors or optic nerve enhancement.
1. Post-treatment findings without evidence of measurable nasopharyngeal tumor.2. Unchanged mild scattered cerebral white matter T2 hyperintense lesions may represent chronic small vessel ischemic disease. 3. Bilateral tympanomastoid opacification may be attributable to Eustachian tube dysfunction.4. Diffuse paranasal sinus inflammation.5. The orbits are unremarkable.
