Protein-losing enteropathy as the principal manifestation of constrictive pericarditis.

Constrictive pericarditis represents a rare cause of protein-losing enteropathy due to intestinal lymphangiectasia. We report the case of a patient with an atypical clinical presentation of constrictive pericarditis and protein-losing enteropathy as its principal manifestation; he was successfully treated with pericardiectomy. We conclude that, constrictive pericarditis should be considered in the presence of protein losing enteropathy and also, protein-losing enteropathy should be considered in the differential diagnosis of hypoalbuminemia.
