Is it okay to do a lumbar epidural steroid injection in a patient with a schwannoma or neurofibroma?
The lesion has been stable for years and she elected a while ago to not undergo surgery. To treat the left sided pain I was thinking of an epidural steroid injection (possibly via the transforaminal approach on the left). But I’m not sure if the lesion is a contraindication?

I actually found some info myself: This case report [Transient cauda equina syndrome related to a sacral schwannoma with cauda equine compression after a lumbar epidural block -A case report-.] suggests transient neurological symptoms occurred in a similar situation but with a high volume of injectate. They postulate it’s from volume/mass effect, but it's hard to know for sure. I didn't see any good large studies.
