A case of mesenteric cystic lymphangioma in an adult which caused duodenal stenosis after resection.

INTRODUCTION: We present a rare case of mesenteric lymphangioma in a middle-aged female. PRESENTATION OF CASE: A 56-year-old female was admitted to the hospital with upper abdominal pain. Abdominal computed tomography revealed a multicystic mass surrounding the mesentery. We made the decision to resect the mass, suspecting that was a mesenteric lymphangioma based on additional imaging studies. The tumor adhered strongly to parts of the duodenum and the upper jejunum. In order to preserve the jejunum, we dissected its serosa away from the tumor. Approximately 1 week after surgery the patient experienced a constriction of the third portion of the duodenum. Her symptoms were improved with conservative therapy, and she was discharged from the hospital 62 days after surgery. DISCUSSION: Lymphangioma originating from the mesentery may have cause adhesions due to exfoliated tumor cells; it is necessary to be concerned about postoperative obstruction.
CONCLUSION: The preoperative diagnosis of lymphangioma is based on various imaging modalities.
