 Limited examination for operative planning demonstrates bilateral transfrontal brain electrode lead placement with tips near the level of the subthalamic nuclei. There is decreased T2 hyperintensity surrounding the leads bilaterally. There is no intracranial mass. There is no midline shift or herniation. The ventricles and basal cisterns are unchanged in size and configuration. There is a small left parietal lobe developmental venous anomaly. There is a mucous retention cyst in the right sphenoid sinus. There are scattered T2 hyperintense foci in the calvarium. The extracranial soft tissues are unremarkable.
1. Bilateral deep brain electrode leads with tips near the level of the subthalamic nuclei.2. Scattered T2 hyperintense foci in the calvarium, which are incompletely characterized, but may represent hemangiomas.
