Hello
Thanks for writing to HCM
You shouldn't worry at all.
Cortical cyst is a very common type of
kidney cyst. As it is located at the renal
cortex,it is called as cortical cyst. It is a fluid-filled sac growing in the outer area of the kidneys.
Exact cause is not known.It might be caused by infections,injuries or genetic issues.
Usually very small cysts don't cause any problem.
If the cyst grows larger,patient might have pain or pressure in back or sides.
You need dietary and lifestyle Changes.Take less sodium in your diet and avoid spicy,fried food.
You need follow up scan and proper treatment depend upon size,symptoms etc.
Hope I have answered your question.
Take Care
