MRI help?

[klh]

I am usually pretty good at reading MRI's, but I cannot for the life of me figure out what this is? It (attached) comes from a axial view of my back. I put a arrow showing what I am talking about, the big black round part towards the upper right of the pic. Any body can tell me for sure?

Thanks in advance!

Hi KLH

I cannot read your report pop up to small.

Ken,

Your MRIs conclusion is that you have minimal degenerative changes at L5/S1 with a mild disc bulge posteriorly. There is also mild foraminal stenosis bilaterally at L3/L4. Also noted on the report is an incidental cyst on the left kidney.

Note: I disabled your link in the post above because it had all of your identifying information on it.

As far as the renal cyst goes quite a few have them. They are graded on complexity with anything over a three on the Bosnic scale needs a ultrasound or CT, say yearly. I'm not that smart, I just have one too. Had it for 20+ years and has always been a Bosnic II the whole time. I never know it is there. It is one of those not cancers but on occasion does step over the line. With a Bosnic II, on source said as many 16 % can have renal cancer just from this level. Most kidney cancers are renal cell type and rarely metastasize distally, but will over time grow out and invade. Bosniak renal cyst classification | Article | Radiopaedia.org

This seems like on of those thinks you mark your calendar to get done every year with your GYN exas.
