History of SRS for single brain metastasis No diffusion restriction is seen to suggest acute ischemia. No susceptibility weighted artifact is seen to suggest intracranial hemorrhage. Periventricular and subcortical white matter T2/FLAIR hyperintense foci is likely secondary to moderate small vessel ischemic disease and/or posttreatment changes. No mass lesion or abnormal areas of enhancement are present. The CSF spaces are appropriate for the patient's stated age with no midline shift. Normal vascular flow voids are present in the major intracranial vasculature.Mild mucosal thickening is seen in the maxillary sinuses. The imaged portions of the orbits are intact.
1.No evidence of intracranial metastases.2.No change in moderate chronic small vessel ischemic disease and/or post treatment changes.
