Last Update Posted : September 26, 2013
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;
- Some schwannomas keep growing, the others do not.
- Foraminal schwannomas do not usually grow.
The investigators analyzed natural history and characteristics of 56 spinal schwannomas observed initially with accurate and reliable methods. Here the investigators displayed growing pattern and differential point of spinal schwannoma.
