RationaleSpinal cord stimulation (SCS) is one of the invasive treatments of complex regional pain syndrome (CRPS). The positive effect has been observed for several years after implantation. However, infection is a common cause of SCS failure and device removal.Patient ConcernsHere we describe a case of latent infection at the implantable generator pocket site 9 years after SCS implantation in a patient with CRPS.DiagnosesA 52-year-old patient was diagnosed with type 1 CRPS. The right foot pain was intractable with standard treatments. SCS implantation was performed and SCS worked well without complication. Nine years later, the patient revisited due to pain, tenderness, and redness at the abdominal wall for 2 weeks. The right foot pain was maintained with NRS 4 for 8 years, and the stimulation stopped 1 year back. SCS infection was diagnosed.InterventionsThe patient underwent SCS removal surgery.OutcomesAll SCS devices were removed successfully. The patient was discharged without any complications.ConclusionsWhile uncommon, infection after SCS implantation can occur even 9 years later. Immediate diagnosis, proper antibiotics, and surgical removal could be needed to prevent further spread of infection and better prognosis.Copyright © 2023 the Author(s).
