[|Human|] I had a CT scan of my kidneys for a possible kidney stone. I see the results said I had a 18 mm simple appearing cyst in the midportion of the left kidney anteriorly. There is also a vague high density in the lower pole of the right kidney laterally possibly representing a high density cyst. Could either of these things be causing me lower pelvic pain and lower back pain?
[|AI|]  Welcome to Chat Doctor. 1. The renal cysts do not cause any pain - it's just an incidental finding on CT scan.2. The 18 mm cyst is a simple cyst, and the high density cyst shows some complex features - however does not need any active intervention. To be safe side get a KFT - kidney function tests done.3. The low back pain can be a spinal and disc pathologies causing pressure effect on the nerve may give such pains.4. Initially you try back exercises on daily basis - only to the extent your body supports. That will give you relief.5.If it does not give any relief you may need to get an MRI scan for disc and nerves and treatment could be physiotherapy.6. Renal cysts should be followed-up in the subsequent scans. Good luck. Hope I have answered your query,anything to ask ? Do not hesitate to ask.http://doctor.ChatDoctor .com/doctors/ Chat Doctor.
