Abstract

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

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:

- 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.
