Abstract
A 65 year-old man was hospitalized due to lower abdominal pain. Abdominal computed tomography revealed a thickened appendix resembling bunches of grapes and opacity of fat tissue. An emergency operation was performed under the diagnosis of appendiceal diverticulitis. A portion of the appendix had perforated. We confirmed a perforation of diverticulum with contrast radiography and a pathological exam. Because the frequency of perforation in appendiceal diverticulitis has been estimated to be much higher than that in ordinary appendicitis, a symptomatic appendicitis with diverticulum and/or an appendiceal diverticulitis should be operated on regardless of the degree of inflammation. On the other hand, it is very difficult to diagnose appendiceal diverticulitis preoperatively. We herein report on a case with appendiceal diverticulitis diagnosed preoperatively with a review of the literature.
