Acute appendicitis is one of the most common causes of abdominal pain. CT image and /or pelvic ultrasonic scan are excellent resources to assist in diagnosis. The common locations to examine are retroceacal, pelvic and retroileum. The size of a normal appendix is less than 6 mm in diameter and the wall is less than 2 mm thick. The associated findings are periappendiceal edema with or without fluid collection and/ or calcified fecalith in the lumen. In pregnancy and pediatric groups, ultrasound should be performed. The differential diagnosis is diverticulitis.
