Recurrent intrathecal catheter-tip granuloma formation on a replaced system delivering low dose/concentration fentanyl and bupivacaine: a case report

ICTG formation is uncommon but can be a devastating complication of IDD if not properly diagnosed in a timely fashion. Repeat ICTG has only been documented twice in the literature, and ICTG with low dose fentanyl in combination with bupivacaine has not been reported. Despite using regimens and techniques to reduce the risk of ICTG formation, one must judiciously surveil their patients for the dreaded ICTG complication.
