On my staging scans, there were two incidental findings: 1) a 2mm cyst on the liver and 2) diverticulosis of the sigmoid
colon. I have two questions. One, I was told that the liver cyst was indeed a cyst because it only showed up on the CT done
with contrast, but not on a subsequent PET/CT done without contrast. Is this true, or should I ask for an abdominal u/s to
verify the cyst is just a cyst?
Two, I know that diverticulosis of the sigmoid colon is very common. However, it does not seem that it would be common in a
38 year old who eats a lot of fruits, vegetables and whole grains. What would a differential diagnosis of diverticulosis be?
My concern is that lobular cancer tends to spread to the gastointestinal area and is hard to see on scans, and I wanted to
know if lobular mets could mimic diverticulosis. Thank you in advance.
