[Chylopericardium as a rare cause of a "large" heart shadow--2 case reports].

Two cases with the diagnosis of asymptomatic chylopericard were evaluated. One was a 20-year old girl who had been operated on for intrathoracic lymphangioma and chylopericardium that existed since birth, and who developed a chylothorax after the operation. The second case report concerns a 22-year old man who had been suffering from a posttraumatic asymptomatic chylopericardium for two years and who is being treated conservatively "Low-fat diet").
