Answer

Appendicitis may occur for several reasons, such as an infection of the appendix, but the most important factor is the obstruction of the appendiceal lumen (see Pathophysiology and Etiology). Left untreated, appendicitis has the potential for severe complications, including perforation or sepsis, and may even cause death (see Prognosis). However, the differential diagnosis of appendicitis is often a clinical challenge because appendicitis can mimic several abdominal conditions (see Diagnostic Considerations). [12]
