Burr hole trepanation for chronic subdural hematomas: is surgical education safe?

abstract：:Intraspinal nerve-sheath tumours are generally slow growing and are diagnosed after causing symptoms such as back pain and progressive neurological symptoms. We present a rare example of multiple schwannomas located in the thoracolumbar spine in a previously asymptomatic patient who developed severe neurological defic...
