inflammation of the vermiform appendix. Acute appendicitis, which has become common this century, usually affects young people. The chief symptom is abdominal pain, first central and later (with tenderness) in the right lower abdomen, over the appendix. Unusual positions of the appendix may cause pain in different sites, leading to difficulty in diagnosis. Vomiting and diarrhoea sometimes occur, but fever is slight. If not treated by surgical removal (appendicectomy) the condition usually progresses to cause an abscess or generalized peritonitis. Conditions that mimic appendicitis include mesenteric lymphadenitis, acute ileitis (see Crohn's disease), pyelonephritis, and pneumonia. Chronic appendicitis was a popular diagnosis 20-50 years ago to explain recurrent pains in the lower abdomen. It is rare, and appendicectomy will not usually cure such pains.
