Lymphangiectasia, also known as "lymphangiectasis",^[1] is a pathologic dilation of lymph vessels.^[2] When it occurs in the intestines it is known as intestinal lymphangiectasia, colloquially recognized as Waldmann's disease in cases where there is no secondary cause.^[3] The primary defect lies in the inability of the lymphatic system to adequately drain lymph, resulting in its subsequent accumulation and leakage into the intestinal lumen.^[3] This condition, first described by Waldmann in 1961, is typically diagnosed in infancy or early childhood.^[3] However, it can also manifest in adults, exhibiting a broad spectrum of clinical symptoms.^[3]
