Both intraabdominal cystic lymphangioma and chylolymphatic mesenteric cyst present as huge abdominal mass and both have chyle as their content. Hence the only way to differentiate between these two conditions is by histopathological examination which is extremely important as lymphangiomas are more invasive and relapsing than mesenteric cyst. Here we report a rare case of huge abdomen due to cystic lymphangioma arising from lesser omentum that did not have recurrence for more than six years after surgical excision.
