The appendix duplication is a sporadic malformation in which the horseshoe form is the uncommon described variant. To our knowledge, we report the first Moroccan case of a horseshoe appendix in a girl admitted to managing of pain at the right iliac fossa.

Through this article, we present a very rare case of appendicular duplication. It has not been objectified in radiological exploration and discovered by chance during the operation. Resection then closure of the appendicular bases allowed our patient to heal. The objectives of this work is threefold: i) to report this sporadic case of horeshoe appendix, ii) to emphasize the importance of suspicion of appendicular duplication in appendicular syndrome and iii) to recommend the exploration of the ileoceacal region to avoid surgical complications and medicolegal problems.

Our case report shows that we have to take into consideration this sporadic presentation of appendicular syndrome and this even in the absence of radiological signs. Our work brings enriched the literature by a new case of horseshoe appendicitis highlighting the importance of surgical treatment.

We report a case report of an appendix duplication witch is a very rare congenital malformation. To date, only fifteen cases were published.

• Acute appendicitis
• Duplication

Acute appendicitis, which requires immediate surgical intervention, is an important diagnosis in patients with acute abdomen. However, developmental abnormalities may interfere with the preoperative diagnosis and surgical treatment in some cases. Agenesis and atresia of the cecal vermiform appendix is an extremely rare clinical diagnosis. In addition, preoperative diagnosis may be difficult in some cases. Thus, diagnosis of the congenital absence of the vermiform appendix requires a thorough exploration of the retrocecal and ileocecal regions. A 59-year-old male was admitted from the emergency services with right lower abdominal pain. A celiotomy was performed with the suspicion of acute appendicitis. However, an atresia of the vermiform appendix was observed. The patient’s appendix was thus removed. Pathological examination confirmed suppurative appendicitis. This case underlines the importance of the clinical entity for surgeons who may deal with a similar case.

A 37-year old male presented with an acute abdomen suggestive of an appendiceal perforation. Urgent laparotomy showed a duplicated appendix with one of the lumens involved with appendicitis and a focal peri-appendicular abscess while the other lumen had a localized appendiceal cancer. Recognition of congenital intestinal duplications in adults is important to avoid serious clinical consequences.

Combined duplication of the colon and vermiform appendix is one of the rare congenital anomalities of the alimentary tract. Only a few cases have been reported in the adult population. A 28-year-old man presented to the clinic with a mass in the right flank. Imaging showed only a hydronephrotic atrophic kidney. The final diagnosis was only available at exploration. Combined duplication of the tubular colon and vermiform appendix was confirmed histopathologically. The patient was treated with nephrectomy and complete resection of the duplicated colon and vermiform appendix. The patient recovered uneventfully, and has done well for the past year. This is believed to be one of the first reports of combined duplication of the tubular colon and vermiform appendix as a cause of hydronephrotic atrophic kidney in an adult patient.
