Adult mesenteric lymphangioma is relatively rare. A 20-year-old woman seen for lower abdominal pain 4 years ago and diagnosed a mesenteric cyst. But she suspended coming our hospital because of disappearance of pain. This time she was admitted for left flank pain. US, CT, and MRI showed a cystic lesion with septal structures. After a small bowel series and angiography, we diagnosed the condition as bleeding, infection, or torsion of a mesenteric cystic tumor. Laparotomy showed a soft white 9×9×6 cm tumor in the mesentery of the jejunum with thickening of serosa from the tumor to the mesentery root. The tumor was excised with about 20 cm of the jejunum. Histological findings showed a multiple cystic tumor with lymphatic dilation. The cyst was filled with chyle. Histological examination confirmed the diagnosis of lymphangioma. We review the case in the context of the Japanese literatures.
