Bosniak renal cyst - type II

Case contributed by Andrew Dixon

Triphasic Renal CT


Left upper pole renal cyst with a single thin focus of wall calcification. Right lower pole renal cyst with a single thin septation. Both cysts fall into the 'minimally complex' Bosniak II category and can be confidently said to be benign without follow-up imaging required.  

Incidental findings include mesenteric panniculitis, mildly fatty liver and uterine fibroids. 


Illustrative example of a Type 2 cyst.
