Simple renal cyst also called renal cortical cyst. 

What is it? 

Renal cortical cyst is a sac of clear fluid forming within the cortex or outer part of the kidney. 

Cause:

Usually the result of obstruction of microscopic renal tubules within the kidney. Exact etiology of cyst of kidney is still unknown. 

Above ultrasound images show a typical cortical cyst in left kidney. 

This cyst of the left kidney is in the upper part and bulging outwards- so called exophytic cyst. 

Prognosis: such renal cortical cysts don't require treatment as such but need to be followed by repeat scan after a few months. If it grows larger- more than 5 cms or gets infected they need surgical treatment.
