Liver mass

Following an abdominal ultrasound to check my gallbladder, the doctor ordered a CT scan because 2 hypoechoic masses were noted on my liver.  Have not received the results from the CT scan.  What are the possible causes of the masses?

I have 8 masses on my liver also. They were found in June of 07' after I had an ultrasound for abdominal pain. I am 26 years old. Don't be surprised if they order an MRI, then a liver biopsy. That is what I have been through. They came to the conclusion that my masses were benign and were caused by my Birth control pills that I had taken for 8 years. I have had a CT scan every 6 months now and they seem to be shrinking. My Liver enzymes are also elevated and I have been controlling that with diet and exercise. But I know it's hard not to worry..I've been in your shoes. Try not to ...and I hope every thing turns out ok for you.
