BACKGROUND: Spinal cord stimulators (SCSs) are a widely used intervention for managing chronic neuropathic conditions. SCSs are considered safe, but rare complications can arise, typically attributed to spinal cord compression or contusion. Spinal cord infarction as a complication of SCS placement has not been previously reported in the literature.

CASE REPORT: A 76-year-old woman developed spinal cord infarction resulting in right leg paralysis following SCS placement. Immediately postprocedure, there was bilateral lower extremity paralysis with partial recovery of the left leg but persistent right leg paralysis. Extensive changes consistent with cord infarction from C7-L2 were seen on spinal magnetic resonance imaging, and vascular compromise of spinal arterial supply was suspected. Despite medical management and rehabilitation, no significant improvement in right leg function was observed.

CONCLUSIONS: This case highlights spinal cord infarction as a rare but serious complication of SCS implantation. Physicians should be aware of potential vascular injuries and counsel patients accordingly.
