title: MRI findings of the cavernous sinus metastasis with inferior extension mimicking a nasopharyngeal carcinoma with cavernous sinus invasion.
abstract: The authors report the MRI findings in a patient with cavernous sinus metastasis with inferior extension to the nasopharynx, mimicking imaging findings of the advanced nasopharyngeal cancer with the skull base, and intracranial extension. Findings of denervative atrophy of the masticator muscles and obstruction of the Eustachian tube resulting in fluid retention of mastoid air cells are seen in both processes.
