  • Abstract
  • Look Inside

 Intramedullary schwannoma with no evidence of neurofibromatosis is very rare. We report extramedullary schwannoma had grown into the spinal cord. It was impossible to differentiate this tumor from other intramedullary tumors and difficult to preoperatively know its exact relation to the spinal cord by MRI. We almost could suppose its relationship between the tumor and the spinal cord by CTM. We think the tumor was born from dorsal-root Schwann cells in a “critical area” where posterior roots lose their sheaths on entering the pia mater, and grew into the spinal cord.
