I had a cat scan @ emergency room yesterday & they found multiple simple cyst in my liver & a large bilobed cyst in the left hepatic lobe 2cm?

Liver cysts common: Simple cysts are very common on CT and most people would never know they were there unless advanced imaging like a CT is done. The bilobed cyst is difficult to assess without more information. You should see you PCP or a GI doctor to make sure no further testing is needed. Obviously the concern with cyst like structures in any organ is cancer. You should see a doctor soon.
