Yearly surveillance of AVM and meningioma, right side finger and toe numbness, occasional vision "unsteadiness" lasting 1-2seconds. MRI: There is an unchanged extra-axial left parafalcine enhancing mass measuring up to 28 mm, with mass effect upon the superior sagittal sinus and underlying brain parenchyma, but no associated edema. There is mild high T2 signal in the parenchyma surrounding the right central sulcus arteriovenous malformation. 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, skull, paranasal sinuses, and scalp soft tissues are unchanged.MRA: There is an unchanged nidus related to an arteriovenous malformation in the right central sulcus, measuring up to 30 mm. There is no evidence of significant steno-occlusive lesions or aneurysms.
1. Unchanged left parafalcine meningioma.2. No significant interval change in the right central sulcus arteriovenous malformation.
