Redemonstration of an infiltrative T2 hyperintense lesion in the left temporal lobe and extending into the left occipital lobe, parietal lobe, and splenium of the corpus callosum. There is local mass effect with sulcal effacement and effacement of the temporal horn of the left lateral ventricle.Stable additional areas of T2 hyperintensity in the periventricular white matter compatible with chronic small vessel ischemic changes.Postcontrast images demonstrate 2 small nodular foci of enhancement in the left temporal lobe measuring up to 3 mm. There is asymmetrically increased vascularity in the left temporal lobe with dilatation of the temporal branches of the left posterior cerebral artery.The expected intracranial vascular flow voids are present.The paranasal sinuses are clear.
