Case Discussion
This is a classic example of a Bosniak type IV cyst - with an abnormal cyst first identified on ultrasound proceeding to three phase CT imaging.
It is made more difficult by the bilateral cystic renal disease, but the left mid/upper pole cyst contained a significant solid element.
The patient is due for a total nephrectomy - the histopathological outcome will be added when available.
