Parasites VS. Stones in the Liver and Gallbladder

If parasites are located in the gallbladder or liver, can they sometimes be mistakened for "gallstones" or " liver stones " - on HIDA Scans or Cat Scans?

Also, can the symptoms of parasitic infections of the liver and/or gallbladder MIMIC the symptoms of gallstones, gallbladder disease, or liver congestion?

I was wondering about this because of the symptoms that I am experiencing. And, I also wondered about why some individuals still experience upper abdominal pain and discomfort after having their gallbladders removed. Perhaps, the problem may have been due to undiagnosed parasites in the liver or gallbladder, instead of "stones" or a diseased liver/gallbladder?

I have not had a HIDA, CAT scan, or gallbladder surgery performed. However,
I would like to hear others' comments to get some insight as to what I may be dealing with.

Thanks.
