Perineural Cyst Symtoms and L3&L4 Fusion Surgery

Hey SH - I am wondering if anyone has had Symtoms from a perineural cyst, the cyst forms itself about the roots of the nerves in the spine!  The reason I ask, my pain has been off the charts the last 3 weeks and after not being able to take it anymore I fought to get answers.  Now we have an answer which is removing this cyst it is a very serious surgery that could cause neurological problems, either treated or not treated. I also need to have L3&L4 fused .  Less than 1% experience Symtoms and I’m wondering if anyone has gone through this surgery of having the cyst removed or knows anything about it.  I little history, 45yr old, with DDD, peripheral neuropahy.  I just had C5-C7 fused in my neck on Halloween of 2017.  Ive also have S1&L5 fused in my lower back.  In October of 2016 I had a pain pump installed.  Long story Short my body rejected the pump and it was removed in June 2017.  At which time, I developed a really bad spinal fluid leak which has now developed into this cyst.  As I stated my pain horrible the last 3 weeks or so and my regular meds have not helped at all.  So if anyone out there has any info or had surgery to remove a perineural cyst they can pass along it would be greatly appreciated.  Thank you and hope you all have a great night!  




  • hi michael

    so sorry to hear about this new development after all you have been through.

    i have not experienced any cyst, but i did have a dura tear during my tlif l4-s1, so would be interested in your symptoms.

  • AJ - Good morning and thank you for the response.  Symtoms with perineural cyst or Tarlov cycst are sciatica pain, pain in the buttocks, muscle weakness, pain in the lower back, pain down the back of the legs, loss of bladder control and sexual dysfunction.  That’s what made it tricky to diagnose, my symptoms can be caused by the herniated disc at L3/L4 or the cyst.  The kicker was the mri and when my regular pain meds really wasn’t helping, because this cyst is CSF fluid based and wraps itself around your nerve roots.  Surgery to remove should only be done as a last resort...what Symtoms are your experiencing from the dura tear? Thank you for the link and I will review.
