Pediatric Radiology > Abdominal > Lower GI > Appendicitis


Appendicitis is the obstruction of the appendiceal lumen resulting in distention of the appendix, superimposed infection, ischemia, and eventually perforation. The incidence is 7-12% of the Western world population, occurring in all ages. Symptoms include fever (56%), nausea and vomiting (40%), RLQ pain - McBurney sign (72%), and leukocytosis (88%). In 20-30% of patients, however, the classic signs and symptoms are not present. Perforation is a serious complication. Surgical removal of the appendix is the treatment.
