Abstract
Mesentric lymphangioma is a rare disease, particularlly in adults. Recently we have encountered an adult case. The case wa a 36-year-old female with the complaints of abdominal mass and oppressed sensation. Palpation of the abdomen revealed an approximately pherical, smooth surface, elastic hard, and movable tumor 6cm in surface, elastic hard, and movable tumor 6cm in diameter. Ultrasonography showed a multilocular cystic under the umbilicus on standing position. From the result as well as various examinations, it was diagnosed as intraperitoneal parenteral cystoma. On laparotomy under general anesthesia, a dark-red multilocular cystoma in the transverese mesocolon was found and excised as "en-bloc". Histopathologic findings indicated mesenteric lymphangioma. Postoperative course was uneventful.
In addition, the ethiologic investiagion of the disease in adults and its characteristics were disccussed in domestic 32 cases collected, and the significant diagnostic value of ultrasonography is emphasized.
