Acute appendicitis in a patient with appendiceal duplication

Acute appendicitis is a common pathology in emergency surgery. Some anatomic anomalies can complicate its correct diagnosis and management. Appendiceal duplication is a rare congenital abnormality. Its incidence rates 0.004% among patients operated for acute appendicitis or other surgical pathology. Preoperative diagnosis of appendiceal duplication is extremely difficult and it can be mistaken for other intra-abdominal disorders in some cases. In this paper we report a case of appendiceal duplication in a patient who underwent appendectomy on two separate admissions.
