DBS lead with possible lead breakage. Preoperative planning for possible replacement. Limited examination for operative planning demonstrates bilateral transfrontal DBS lead placment with tips near the level of the subthalamic nuclei. No obvious lead discontinuity intracranially is appreciated. The right lead is minimall inferior as compared to the left. There is T2 hyperintensity surrounding the leads bilaterally.No intracranial mass or mass-effect. No hydrocephalus or extra-axial fluid collections.
1. Bilateral DBS leads with tips near the level of the subthalamic nuclei with the right lead slightly more inferior than the left. No obvious intracranial lead discontinuity is appreciated.2. T2 hyperintensity surrounding bilateral leads is of uncertain significance and may represent edema related to inflammatory response (Englot DJ, et al. Stereotact Funct Neurosurg. 2011;89(5):311-7).
