The causes of complications and failure of spinal cord stimulator (SCS) include migration, breakage, disconnection of the lead, fibrosis, effluence of cerebrospinal fluid, and infection-induced meningitis. Here, we report an unusual case of leakage of implantable pulse generator (IPG) batteries during SCS removal. A 76-year-old woman diagnosed with complex regional pain syndrome type 1 underwent SCS implantation 13 years ago to treat her arm pain. She visited the hospital for SCS removal as it was nonfunctional. Upon incision at the IPG pocket site, a clear milky pus-like liquid discharge was observed. An abscess was suspected. However, white corroded areas were observed around the IPG after the completion of the drainage. Although battery leakage from the IPG had occurred, the patient had no symptoms because the granulation tissue had prevented the absorption of the leaked products from the battery into the systemic circulation. Therefore, we recommend replacing the IPG after 9–10 years or as the product manufacturer recommends.
