Paraclinoid meningioma status post RT: surveillance MRI. There are postoperative findings related to left temporal craniotomy with a substantial defect in the anterior left temporal lobe and confluent T2 hyperintensity in the surrounding brain parenchyma, mainly related to encephalomalacia. The extra-axial enhancing tumor in the left paraclinoid region, appears to be slightly smaller, measuring up to 14 mm, previously 16 mm. The mass partially surrounds the internal carotid artery, without apparent significant narrowing of the flow void. The tumor also continues to abut the prechiasmatic segment of the left optic nerve. There are unchanged mild nonspecific foci of cerebral and brainstem white matter T2 hyperintensity, which may represent chronic small vessel ischemic disease. There is no evidence of acute intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unchanged, including a left temporal scalp lipoma.
Apparent slight interval decrease in size of the treated residual left paraclinoid region meningioma.
