An Adult Case of Significantly Shrunken Cystic Lymphangioma in the Mesentery after Infection

Abstract

The patient was a 51-year-old woman with chief complaints of abdominal pain and anorexia. A blood test showed a high degree of inflammation. Abdominal computed tomography showed a multifocal cystic lesion in the abdominal cavity, 119×154 mm in size, with inflammation. A diagnosis of abdominal lymphangioma with infection was made, and the patient was treated with antibiotics. The abdominal pain and inflammation disappeared with antibiotic treatment. Magnetic resonance imaging 8 weeks after onset showed that the lymphangioma had shrunk significantly to 28×68 mm. Laparoscopy showed a lymphangioma in the ascending mesocolon, and laparoscopic ileocecal resection was safely performed. The pathological diagnosis was cystic lymphangioma of colonic mesentery.

Cystic lymphangioma, which is congenital and rare in adults, tends to grow rapidly and regress after infection or bleeding. The clinical course of this case is presented along with a review of the relevant literature.
