The double appendix is an extremely rare condition. It can be overlooked by imaging methods. It is usually noticed as a result of abdominal exploration during surgery in cases operated for acute appendicitis. Both can be located close to each other in the cecum, or one can be in the cecum and the other anywhere in the gastrointestinal tract. Both may be inflamed at the same time, or one may be inflamed while the other may be normal. It is especially important in patients with appendectomy in the differential diagnosis, as it may cause a recurrent acute abdomen due to acute appendicitis. In this case report, it is aimed to share the clinical, laboratory, and radiological features of a case with a double appendix.
