Primary Intestinal Lymphangiectasia: A case report

Primary intestinal lymphangiectasia (Waldmann’s disease) is a rare protein-losing enteropathy which is mostly seen in young children. A 22-month-old male baby presented with a 1-week history of abdominal distension, chronic loose stools, recurrent ear infections, and failure to thrive. He had edematous eyelids and non-pitting edema of his hands and feet. The patient was diagnosed via endoscopic visualization and biopsy of the lymphangiectasia in the small bowel. He was managed through dietary restriction with a high-protein, low-fat diet. The patient subsequently had resolution of the diarrhea and an increase in albumin and total protein on labs. We describe a rare case of primary intestinal lymphangiectasia and highlight its clinical presentation, diagnosis, and treatment.
