(a) Unremarkable head computed tomography (CT) performed early on postoperative day (POD) 1. (b) Stat head CT later on POD 1 showing marked left-sided peri-lead edema extending into the centrum semiovale with cystic cavitation and trace right-sided edema. (c) Follow-up head CT at 3-month clinic visit showing significant resolution of the peri-lead edema and cystic cavitation. The leftmost image corresponds to the top yellow line in the rightmost image, and the middle image corresponds to the bottom yellow line in the rightmost image.

Head CT performed on early postoperative day (POD) 1 was unremarkable [Figure 1a]. Stat head CT performed revealed marked left-sided peri-lead edema extending into the centrum semiovale with cystic cavitation and trace right-sided edema [Figure 1b]. Follow-up CT scans at the time showed significant resolution of the peri-lead edema and cystic cavitation [Figure 1c].
