The diagnosis is made using a combination of history, physical examination, and laboratory tests plus an elevated temperature and white blood cell count. A positive imaging study is helpful and gives reassurance about the diagnosis. In equivocal cases, serial observations and studies over time improve the accuracy of diagnosis, but at the risk of an increasing rate of perforation.
