The highest incidence occurs in adults 20 to 40 years of age. There remains a fair amount of controversy in the literature regarding the optimal antibiotic choice and the mechanism of drainage. The objective for the Emergency Physician remains to make an accurate diagnosis, to institute appropriate care, and to arrange timely follow-up.
