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.
