Cisto de mesentério

Mesenteric cyst is a rare abdominal disease, with a higher incidence among women and 1: 250.000 incidence among hospitalized adults and 1: 200.000 among hospitalized children. Thereby, we report a case of a 10 years old child, male, presenting a large mesenteric cyst, which occupied almost all the abdominal and pelvic cavities and treated by resection during laparotomy.
