Right cavernous sinus meningioma. Status post resection and posterior technical radiosurgery. Follow-up. Also, increased pressure and pain at the incision site. There are changes of previous right pterional craniotomy and right cavernous meningioma resection. The residual enhancing tumor involving the right cavernous sinus and extending into the right orbital apex through the optic canal and into the pterygopalatine fossa via the foramen rotundum and inferior orbital fissure is unchanged. There is associated compression of the right optic nerve with atrophy of the remainder of the retrobulbar segment. Dural thickening in the anterior aspect of the right middle cranial fossa is unchanged. The anterior right temporal encephalomalacia adjacent to the resection cavity is unchanged. Likewise, scattered nonspecific T2 hyperintense foci in the cerebral white-matter are unchanged. There is no evidence of new intracranial hemorrhage, mass, or acute infarct. There is an unchanged small left precentral development of venous anomaly. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The left orbit is grossly unremarkable. There is a right maxillary retention cyst. Otherwise, there is minimal scattered mucosal thickening in the paranasal sinuses.
1.The residual right cavernous sinus meningioma with orbital and pterygopalatine extension appears to be unchanged since December 2014.2.Anterior right temporal encephalomalacia and mild cerebral white-matter probable chronic microvascular ischemia are also unchanged.
