 Compared to prior MRIs dating back to October 2012, there is no evidence of significant interval change in the size of a nonenhancing 1.8 x 1.6 cm T2 hyperintense lesion in the left frontal operculum with mild local mass effect. However, this lesion has enlarged mildly when compared to exams from 2011 earlier. Few scattered T2 hyperintense foci in the periventricular and subcortical white matter are unchanged. There is a probable small pontine capillary telangiectasia which appears slightly more prominent perhaps related to technical differences. There is an unchanged right cerebellar development of venous anomaly. The ventricles and sulci are unchanged. There is no acute infarct.
