 Again seen is a right frontal approach deep brain stimulator, which courses in the right frontal lobe and basal ganglia and terminates at the right medial temporal lobe. There is a branching pattern of enhancement with susceptibility effect and punctate T2 hyperintensity in the right thalamus and cerebral peduncle, which is unchanged. Associated calcification is better demonstrated on CT. There is no associated mass effect. There is no evidence of a large acute intracranial hemorrhage or acute infarct. The brain parenchyma otherwise appears unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unremarkable.
1. Unchanged vascular lesion involving the right thalamus and cerebral peduncle which is most compatible with a developmental venous anomaly or capillary telangiectasia. 2. Right frontal approach deep brain stimulator.
