IOTW: Simple renal cyst

Posted on: March 14, 2020, by :

This post illustrates the difference between a simple renal cyst and hydronephrosis. The cyst is located within the cortex, is anechoic, well-circumscribed, does not branch out into the kidney, and is not connected to the ureter. In contrast, hydronephrosis is not well-circumscribed, it branches into the kidney, and is connected to the ureter.
