A Rare Case of Migratory Intradural Extramedullary Schwannoma of Dorsal Spine: A Case Report and Review of Literature
Abstract: Background: Mobile or Migratory intradural extramedullary schwannomas are very rare and have been reported more in lumbar spine and very less in dorsal spine and cervical spine. The exact cause of migration of schwannoma arising from nerve sheath of a spinal nerve root is unclear and are mysterious in cervical and dorsal spine. Mobile schwannomas require careful evaluation of their localisation otherwise it leads to unnecessary laminectomies. We report a 16-year-old male who presented with weakness in B/L lower limbs and unable to walk for 4 months, MRI spine revealed an intradural extramedullary lesion at D1 D2 level of spinal cord. Intraoperatively the lesion was not found. On repeat MRI it was found migrated caudally to D3 D4 level. Patient was reoperated and tumor was found at D3 D4 level and was excised. Histopathology confirmed a benign schwannoma. This is the rare occurrence of caudal migration of dorsal intradural extramedullary schwannoma.
