[Detection of complete common mesentery on CT scan for perforation in acute appendicitis]. / Découverte tomodensitométrique d'un mésentère commun complet par perforation d'une appendicite aiguë.

Complete common mesentery is a rare abnormality in midgut rotation. Its detection is exceptional during adulthood because, during this period, is very often asymptomatic and therefore not diagnosed. Complete common mesentery may be discovered incidentally in patients with ectopic appendicular syndrome, as in our case study. We here report the case of a 42-year old patient presenting with acute clinico-biological pelvic inflammatory disorder. CT scan allowed the diagnosis of complete common mesentery associated with acute appendicitis. Laparotomy confirmed the diagnosis of perforated acute appendicitis associated with intestinal malrotation. Appendectomy outcomes were favorable.
