Intraoperative neurophysiologic monitoring in spinal cord cavernous angioma surgery: a case report

Spinal cord cavernous angioma (SCAA) is a rare tumorous condition that can manifest various neurologic symptoms, and most lesions are needed to be removed surgically. However, since the SCAA positioned intramedullary, tumor resection could have modest risk for development of neuronal injury. Intraoperative neurophysiologic monitoring (IONM) has been widely accepted as an effective tool detecting damage predicting postoperative deterioration in intramedullary spinal surgery. Here, we briefly report representative case surgery with IONM, which showed different patterns electrophysiologic change each lower limb, followed by relevant states. Based on this case, confirm clinical significance application IONM again.
