Laser ablation There are postoperative changes of bilateral frontal lead placement for laser ablation, with the tips at the level of the anterior limbs of the internal capsule bilaterally. There is T1 hyperintensity/enhancement surrounding the distal aspects of the leads which is expected. Expected postsurgical changes also include small amount of pneumocephalus. No large intracranial hemorrhage or significant mass effect is appreciated. No hydrocephalus. Remainder of the brain parenchyma is unremarkable. Major vascular structures are intact. Tiny left maxillary mucus retention cyst.
