“…Nineteen cases were Type B (i.e. two appendixes arising from a single caecum), but not enough anatomical detail was available to classify further [5][6][7][10][11][12][13][14][15][16]. There were six cases of horseshoe appendix and two cases of triple appendix.…”

An anteriorly placed appendix, away from the convergence of the taenia, or a normal appendix in the presence of convincing clinical or radiological signs of appendicitis should instigate a careful examination of the caecal pole and possible exploration of the retrocaecal space for appendiceal duplication. If the patient had previous surgery for congenital abnormalities, Type B1 or Type C duplication should be considered.

“…Because the thorough exploration of the cecum and retrocecal space was not adequately performed during the rst appendectomy, the second appendix had been overlooked. It has been demonstrated that misdiagnosis of duplex appendix has detrimental clinical and medical consequences (15)(16)(17). In a systematic review conducted by Negzvar and colleagues (2018), out of 141 reported cases of duplex appendix, 67.5% were of the B1 type, and 32.5% were of the B2 type, making them among the most common types (18).…”

Background: Duplex appendix, a rare form of vermiform appendix, is seldom encountered. These anomalies are often found incidentally during surgery for other pathologies or occasionally due to their own involvement. Case presentation: Here, we present a case of a 19-year-old male who initially presented to the hospital with right lower quadrant abdominal pain accompanied by nausea, vomiting, and anorexia. Physical examination revealed tenderness at the McBurney's point and rebound tenderness along with visible guarding. Blood counts showed leukocytosis. Abdominal ultrasound demonstrated an enlarged and thickened appendix. The patient underwent laparoscopic appendectomy, and then, 4 months later, he returned to the hospital with pain in the right lower quadrant, tenderness, and rebound tenderness. A diagnostic laparoscopic surgery was performed, revealing another appendix in the retrocecal area. Ultimately, the patient underwent a repeat appendectomy and was discharged from the hospital without complications after one day. Conclusions: Acute appendicitis should not be ruled out definitively in a patient with typical clinical manifestations, especially in those with a history of laparoscopic appendectomy. Complete exploration of the cecum during surgery is the only reliable option to rule out appendix anomalies and prevent future medical complications.
