Conclusion

The duplication of the appendix is rare, and its treatment is challenging. Therefore, every surgeon must be aware of the anatomical variations of the vermiform appendix, and the caecum requires routine visual inspection to ensure that there are no appendiceal anomalies. Duplication of the appendix should be considered in the differential diagnosis for patients with pain in the right iliac fossa, even if the patient reports previously having an appendectomy, especially if a CT scan has not been performed. Misdiagnosis of this situation can lead to life-threatening complications for the patient and medicolegal consequences.
