Hello doctor, I got both an ultrasound and a CT scan done. Ultrasound says: - Appendix is 5 mm - Appendicolith (stone) of 11 mm seen in the lumen CT scan says: - Appendix measures 5.6 mm - No appendicolith seen - No fat stranding or inflammation Currently, I have no fever, no vomiting, and no constant pain — just occasional mild pain in the lower right abdomen. I'm confused: 1. Do I really have an appendicolith or was the ultrasound wrong? 2. Is any treatment or surgery required now? 3. Can this condition stay stable without surgery if I have no major symptoms?
