My sister was having severe abdominal pain and went to the ER. They took a cat scan of her abdominal region and inadvertantly got a scan of the bottom of her lungs. When the doctor got the results he said there were cysts all over both of her lungs. The were quick to say it was cystic fibrosis, but after contacting a cystic fibrosis center they said that the other symptoms were not there. Could you tell me what else this might be?
