Hi, Welcome to Healthcaremagic.com. I had gone through your question I can understand your concern about appendix removal. Apendicitis is a disease which can be clinically diagnosed. It has a clinical method with proper criteria. If it is found to satisfy the criteria is matching with your patient it can be said the patient has Apendicitis. But as you said the scan is normal without any much inflammation there is no need to go for it. Because it is an acute fetal infection needs immediate surgery. If your patient has migratory pain from abdomen to right groin, shifting tenderness, fever, leukocytosis, fever then there are high chances of Apendicitis. Hope my answer will help you and visit in case you have any other medical query. Regards Dr Muzaffer Hussain Parray.
