Patient's Query

Hello doctor,

I had an MRI of my back, and they saw cysts in my kidneys. I had a follow-up ultrasound, and one found to be complex and then a follow-up kidney MRI. In the right inferior pole, there is a complex cyst measuring 0.8 x 0.5 x 0.7 inch with multiple thick septations. Twinkle artifact is seen within a portion of the cyst, which may represent milk of calcium or wall calcification. There is no flow within septations. They said it was an IIF complex cyst and to just follow-up. Are these cysts usually benign and what do they look for on the follow-up MRI's? Currently, I am on Zoloft and birth control.

Hello,

Welcome to icliniq.com.

Relax and do not worry. Bosniak 2F cyst is usually benign. You just need to follow-up regularly. In follow-up, they see any change to grade 3 or 4. If change is present, then you need to get it removed. So, follow up is must at the prescribed schedule.

Patient's Query

Thank you doctor,

How often does a 2F cyst turn into cancer? Is there any certain percent that does? And do these cysts normally go away? How common are they?

Hello,

Welcome back to icliniq.com.

There are 15 to 20 percent chances of getting it turned into malignancy. They usually do not regress on its own. They are fairly common. But, if you are not willing to take risk, then you can get it removed surgically. That is also an option. You need not follow-up also and you will be relaxed.

Same symptoms don't mean you have the same problem. Consult a doctor now!
