Just had a ct scan with and without contrast to check out a left kidney cyst. This was a lower abdomen-pelvis scan. Radiologist notes that lung bases are clear. What does that mean with respect to the entire lung? Also, ct noted a 4.7 centimeter simple cyst in the left kidney. I am 61 years old and understand that is not uncommon. Is this correct. Thanks, Gerry

It means your lungs are normal, and there is nothing to worry about it.

The simple kidney cyst is a fluid filled spherical space within the kidney. A simple kidney cyst has no risk of ‎becoming a kidney cancer and is therefore nothing to worry about. Usually as age progresses 50% of most adults ‎develop cysts in the kidneys which increase in size as well. ‎

If you are over 40 years old , then the chances of you having such cysts increase.

Simple kidney cysts have no clinical implications. Usually, simple kidney cysts do not result in any symptoms and ‎cause no harm to the body. On rare occasions, a cyst may cause symptoms such as flank pain, but this is quite ‎unusual. If a simple kidney cyst is believed to cause pain or another symptom, it can usually be treated by a ‎radiologist who can perform aspiration and sclerosis of the simple kidney cyst under radiographic guidance with ‎ultrasound or CT scanning.‎

You might consult with your doctor for a examination and he might be able to clear all your doubts and anxiety.
