The duplication of the vermiform appendix is a rare anatomical variant. Most of the cases reported with symptomatology of appendicitis and the finding of a duplication of vermiform appendix. A seven year old female, with abdominal septic shock, plain abdominal radiography with distended transverse intestinal loop with air-fluid levels and absence of air in distal colon and rectal ampula. Emergency laparotomy was performed finding a blind loop with secondary necrosis volvulus, with the torsion being at the base of the duplication, connected at the middle portion of the vermiform appendix; desvolvulus and resection was performed in a block fashion with Parker-Kerr technique using a 4-0 polyglactin suture. There are 100 cases of duplication of appendix reported worldwide. In our case, a duplication of the vermiform appendix type A was presented, shown by the surgical findings and corroborated by pathology samples of intestinal tissue featuring smooth muscle tissue and transmural necrosis and fibrinopurulent exudate in serous. Graphical abstract 14 inch long, greenish black blind intestinal loop with necrosis due to volvulus, being the point of torsion connected with the vermiform appendix, and with diagnosis of duplication of the vermiform appendix type A volvulus by surgical findings and pathology samples of intestinal tissue featuring smooth muscle tissue with transmural necrosis. Display Omitted Highlights ? We report the first case of volvulus in a duplication of the vermiform appendix. ? The clinical presentation was with acute abdomen. ? The surgeon should consider always the duplication of the vermiform appendix.
