Mesenteric lymphangioma in adult: a case series with a review of the literature.

Mesenteric lymphangioma is a rare benign tumor with nonspecific clinical features. A case series of three adult patients who had mesenteric lymphangioma is reported along with a review of literature. Two patients presented with painless abdominal swelling who were being managed as a case of abdominal tuberculosis and a third one had features of intestinal obstruction. In our cases, preoperative diagnosis of mesenteric lymphangioma was not suspected and all the patients had laparotomy. Peroperative findings revealed mesenteric masses, which were simulating cavitatory form of mesenteric node tuberculosis. It is stressed that mimicking of mesenteric lymphangioma with a cavitatory form of tuberculosis of mesenteric nodes in areas of high prevalence may lead to its misdiagnosis. Histopathology confirmed diagnosis of mesenteric lymphangioma in each case. Although rare and difficult to diagnose preoperatively, surgical resection is to be considered gold standard treatment for mesenteric lymphangioma.
