Background
Intestinal lymphangiectasia is a rare condition of impaired lymphatic flow. Several forms are recognized: primary or congenital malformation (Waldmann’s disease) [1], or secondary to a related localized obstructing pathology [2, 3]. The elevated pressure of the lymphatic drainage in the intestinal wall results in the leakage of lymphatic fluid and the manifestation of an exudative enteropathy with hypoproteinemia, peripheral edema, low serum gammaglobulin and/or lymphocytopenia. However, asymptomatic cases also have been described [4].
