A mesenteric cyst (MeSH C04.182.473) is a cyst in the mesenterium, and is one of the rarest abdominal tumors, with approximately 822 cases reported since 1507.[1] The incidence is between 1 per 100,000 to 1 per 250,000 hospital admissions.[1]

Tillaux's triad named after the french surgeon Paul Jules Tillaux can be seen in cases of mesenteric cyst. It consists of the following signs:[2]

  • a fluctuating swelling near the umbilicus,
  • freely mobile in the direction perpendicular to the attachment of mesentry,
  • with a zone of resonance around the swelling.
