Arachnoid Web Associated With An Intrathecal Pain Pump

Dorsal arachnoid webs are rare, and there is a lack of understanding regarding which patients are predisposed to forming them. A 52-year-old female, with an extensive spinal operative history and intrathecal opioid pain pump, presented to the emergency department with thoracic spine pain. Imaging revealed an arachnoid web at the T3 level. The patient was taken to the operating room for resection of the arachnoid web and had resolution of her neurological signs and symptoms postoperatively. Our experience suggests that the presence of an intrathecal pain pump may be a risk factor for the development of arachnoid web.
