A 66yo female with diffuse idiopathic sclerosing hyperostosis (DISH) and lower extremity paraplegia had an intrathecal pump placed for failed back surgery syndrome that initially provided appropriate analgesia. Its efficacy deteriorated, and the decision was made to proceed with revision surgery. In the OR, the catheter was adhered to the interspinous ligament unable to be aspirated or removed due to external compression from tissue ossification. The catheter was replaced twice, one of which was placed with neurosurgical assistance with laminectomy. Each time, the catheter eventually became occluded, presumably from external compression related to DISH syndrome.
