Regarding whether stool can look like a mass on CT, it depends. Usually not, but I don't know if you had a CT with IV and oral contrast. It would also depend on whether contrast reached the rectum. If the underlying question is -- "could I have a negative CT and still have CRC," the answer is yes. Colonoscopy is the best test for CRC. A CT could detect extension beyond the serosa of the GI tract and invasion into adjacent organs. However, staging of CRC is more nuanced than that, in terms of determining invasion beyond certain layers of the GI tract wall.
I think that it's probably best to try not to worry before the colonoscopy. The CT was obtained to evaluate abdominal pain. Absence of an answer is frustrating but not all abdominal pain can be explained. At the very least, the CT is reassuring in that it didn't show disseminated disease.
Good luck on your c-scope.
