The Modified Cave-Wallbridge classification is used to describe the location of the appendixes in relation to each other and to the cecum as well as the extent of the duplication. We report a 45-year-old patient who underwent laparotomy for acute abdominal pain. The operative finding was double acute appendicitis in appendical duplication. The appendixes were removed separately, as it was type B duplication. Since appendectomy is the most common abdominal operation, all surgeons should keep this rare clinical entity in mind.EnglishVERMIFORM APPENDIXDUPLEXArticle
