We report a case of mesenteric cyst. The patient, a 59-year-old woman, was admitted with a palpable abdominal mass. By using ultrasonography, computed tomography, magnetic resonance imaging, angiography etc., she was diagnosed as having an intraperitoneal cyst and an operation was performed. The tumor was found in the radix mesentery close to the third portion of the duodenum. The tumor involved the jejunal vessels, but they were able to be separated and the tumor was resected. The tumor was a unilocular cystic mass with a thick wall and the content was a dull yellow fluid. The tumor was histopathologically a pseudocyst with a chronic inflammatory cell infiltration. Adult cases of mesenteric cyst are rare and we discussed the clinical features of mesenteric cysts in adults as compared with those in children.
