What is a Degenerative Cyst?
I finally got a copy of my MRI repots today when I went into have my discogram done, and I have a question.
For Findings, it says:
T11-12 through L3-4 disc spaces are normal
At L4-5, there is disc desiccation and mild posterior disc bulge without nerve root impingement.
At L5-S1 there are bilateral L5 pars defect with minor anterolisthesis of L5 on S1. There is mild posterior anular bulge. A degenerative cyst is noted at the dorsal aspect of the left pars defect. A small effusion is present in the right facet joint. Central canal and foramina are adequately patent.
This is what the report says for the conclusion:
1) Grade 1 L5-S1 spondylolisthesis with a degenerative cyst at the dorsal aspect of the L5 left pars.
2) Minor posterior annular bulge at L5-S1 without evidence of nerve root impingement.
3) Diminished disc height, desiccation and posterior disc bulge without nerve root impingement at L4-L5.
What is a degenerative cyst from #1? What is anterolisthesis? What does it mean when it says "A small effusion is present in the right facet joint."? Is #2 a big deal? No one has ever mentioned that to me. It keeps saying "without nerve root impingement", so wouldn't that mean it is not pressing on a nerve? If that is the case, would it not cause pain?
My discogram today was incredibly painful, and I still am in lots of pain (more than normal) which leads me to believe that my discs are causing some of the pain.
I just would like some help interpreting these results.
