Epidural Granuloma after Intrathecal Pump Implantation in the Spinal Cord: A Case Report

Intrathecal pump (ITP) is a procedure performed for pain control in patients with cancer pain and refractory pain. Complications such as catheter-related infection, granuloma, and migration may occur, so continuous management is required. In this case, ITP insertion was performed due to central cord syndrome that occurred after a traffic accident. T-L spine computed tomography was performed due to persistent pain exacerbation 22 months after insertion, and epidural granuloma was confirmed. After that, granuloma removal and ITP revision surgery were performed, and pain control has been good so far. The purpose of this case was to investigate the risk factors and evaluation methods for catheter-related granuloma.
