Single-Staged Management of Pediatric Neuropathic Scoliosis with Intradural-Extramedullary Schwannoma and Improvement in Intraoperative Neuromonitoring: A Case Report
2020
CASE A 16-year-old girl with lumbar prominence presented to our outpatient clinic complaining of sporadic back pain without paresthesia. Radiographic investigation revealed a 68° left thoracolumbar curve with the apex at L1. Preoperative magnetic resonance imaging identified a mass at T10-11, subsequently confirmed by pathology as a schwannoma. She was treated surgically with resection and posterior spinal fusion in a single-staged procedure under neuromonitoring guidance. Intraoperative improvement in motor evoked potentials after resection informed the decision to perform simultaneous deformity correction. CONCLUSION We discuss the unusual coincidence of a schwannoma with scoliosis and our management algorithm based on operative changes in neuromonitoring.
