Findings
Thanks for your question on Chat Doctor. In my opinion you should not worry much about your CT report. Subcentimetric atelectasis and nodules are common feature in old age or due to past pneumonia.  So no need to worry much as it is a benign thing, not indicating any Infection or tumor. Pseudo tumor in kidney can also be normal variant and accidental finding. And if you are not having any abdominal symptoms than no need to do anything for few scattered diverticulosis. So over all your CT report is normal.
