Follow up for progression of glomus tumor left skull base. Neck: There is no significant interval change in size of the well-defined enhancing mass containing flow voids in the left post-styloid parapharyngeal space with slight extension into the left posterior fossa through a widened jugular foramen, as well as into the middle ear cavity. The tumor abuts the left cerebellar hemisphere. Overall, the mass measures up to approximately 4.5 cm. There appears to be associated compression of the left sigmoid sinus and upper internal jugular vein. The left internal carotid artery is deviated anteromedially. There is no significant lymphadenopathy in the imaged portions of the neck. The salivary glands are unremarkable. There are secretions in the left posterior ethmoid sinus. There is partly imaged nonspecific patchy posterior cerebral white matter T2 hyperintensity.Brain: There is no evidence of intracranial hemorrhage or acute infarct. There is diffuse patchy cerebral white matter T2 hyperintensity. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. There is a persistent left trigeminal artery. The orbits are grossly unremarkable.
1. No significant change in size of the left jugulotympanicum paraganglioma, measuring up to approximately 4.5 cm.2. Persistent left trigeminal artery.
