There is a nodular area with high T2 signal and mild enhancement at the junction between the right carotid and retropharyngeal spaces just inferior to the skull base that measures up to 15 mm. There is otherwise no significant upper cervical lymphadenopathy. There is no evidence of skull base of adjacent intracranial tumor. The orbits are unremarkable.
