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