Hi, I have gone through your question and understand your concern.

Bulging disc is a common finding on spine Mri, but is quite never related to the reason why people do the mri. It tends to be central and does not compress the nerve roots to cause symptoms. The small hernieted disc is a common finding as well, with several studies reported to be found up to 27% of the spinal mri-s with no treatment indication. Still, those in the recess (lateral) can cause nerve root compression because there is less space for the nerve to tolerate any compression. But, for this condition to need any treatment there ahould be specific signs associated with this hd. Since your hernieted disc is paracentral I would not consider it to cause any problem. So overall I would consider this exam within normal limits, except for the renal cyst, which should be evaluayed by a nephrologist.

Hoping that this answer was satisfactory, please feel free to ask further questions.

I wish you good health
