Right cavernous sinus meningioma: surveillance. There are postoperative findings related to right pterional craniotomy with encephalomalacia and gliosis in the anterior right temporal lobe. There is a dural-based, enhancing mass in the right cavernous sinus region, measuring up to 12 mm in thickness, which is not significantly changed. A petroclival portion of the tumor abuts the pons, extension of the tumor into Meckel's cave compresses the trigeminal nerve roots, and sellar extension of tumor abuts the pituitary gland. There is persistent marked narrowing of the right integral carotid artery by the tumor. There are a few scattered nonspecific foci of cerebral white matter T2 hyperintensity. There is no evidence of intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The orbits are grossly unremarkable.
No significant interval change in the right cavernous sinus region meningioma.
