Question: I have exophytic cortical cysts in the upper left pole. What does it mean? Is it serious? I’m very worried. Please help me.
Answer: Thank you for your consultation. Firstly, I want to give you an introduction of exophytic cortical cyst.
The cortical cyst refers to a very common type of kidney cyst. Because it is located at the renal cortex, it is called the cortical cyst. It is a fluid-filled sac growing in the outer area of the kidneys. You might have one, or you might have several, and they can affect just one or both kidneys.
“Exophytic” means that the cyst grows out of' and can be seen as a feature of certain renal tumors. It may present even in benign and noncancerous tumors.
Generally, one small exophytic cortical cyst can’t change the structure of renal cortex, so patients usually don’t have any symptom. However, as the cysts grow bigger and bigger, they will compress their surrounding cortical tissues and affect the function of glomeruli and kidney tubules. Then, some symptoms may occur. Therefore, I need to know your cyst’s size to see how serious your condition is.
