Patient's Query

Hi doctor,

I was in an emergency last night because of 48 hours of pain that moved to my right lower abdomen. Also, I am not eating, and I have severe diarrhea if I do. They said my white blood cells were a bit elevated. The CT scan without contrast did not show an inflamed appendix. Now it is the next day, and the pain is still there along with a burning kind of feel. What could be the problem? Can a CT scan miss appendicitis?


Welcome to icliniq.com.

  • CT scan could not miss a case of appendicitis unless the medical personnel who viewed the CT scan were not qualified enough for correct interpretation of the scan.
  • Crohn's disease if accompanied by severe diarrhea and no fever.
  • Abdominal aortic aneurysm, but should have appeared in CT scan. Please send me a picture of the CT scan to confirm the diagnosis.

Patient's Query

Hi doctor,

Is the CT 100% accurate? When should I seek medical care if this continues?


Welcome back to icliniq.com.

  • Yes, CT scan is very accurate for diagnosis of appendicitis.
  • You should seek medical care if there is a fever of above 101 degrees, stool that contains blood or mucus, blood in urine, vomiting of blood, pain spreading to back or groin, painful urination or persistent nausea and vomiting.
