NCT01951365

Brief Summary

Spinal intradural schwannoma detected incidentally increased recently. Because there is little knowledge about natural history of spinal schwannoma, there is no consensus of treatment. Our hypothesis is as follows;

  1. 1.Some schwannomas keep growing, the others do not.
  2. 2.Foraminal schwannomas do not usually grow.

Study Population

All patients diagnosed of spinal IDEM schwannoma in 2 institutes

You may qualify if:

  • All patients who were diagnosed of spinal IDEM schwannoma by MR imaging and checked follow-up MR imaging not undergoing surgical resection (including radiosurgery).

You may not qualify if:

  • \) surgical resection at the diagnosis; 2) von Recklinghausen' disease (neurofibromatosis); and 3) recurred or residual tumor.
