I recently had an ultrasound of my kidneys on December 23,2013 have not seen my docter yet but have a scheduled date in jan.2014.The findings were a 16mm cyst in the interpolar region . It was labeled simple cyst also the main portal vein is obscured as well. Under impression it says probable hepatic steatosis simple cyst in left kidney poor visualization of the right kidney. The inferior vena cava mainportal vein and pancreas are also not seen because of patient habitus . If these regions are of clinical concern, consider CT scan what does all this mean?
