Fig. 1From: Acute symptomatic peri-lead edema 33 hours after deep brain stimulation surgery: a case reportRadiographic time course of peri-lead edema. a Coronal and axial slices of computed tomography obtained 1 hour after surgery with no evidence of edema. b Computed tomography obtained 33 hours after surgery demonstrating evolving left peri-lead edema, especially along the proximal third of the deep brain stimulation lead. c T2-weighted MRI sequences obtained 46 hours after surgery showing significant peri-lead edema extending the entire length of the left lead. d Computed tomography obtained 8 days after surgery showing normal postoperative changes with no evidence of peri-lead edema. The white arrows highlight the peri-lead edema. Scale bar – 1 cm. A anterior, L lateral, M medial, S superiorBack to article page
