A case of spontaneous chylous pericardial effusion in Poland syndrome.

Chylous pericardial effusion is an uncommon entity that is most commonly associated with post-cardiac surgery, in particular aortic valve and minimally invasive cardiac surgery. Post-radiation therapy, infection, mediastinal neoplasm, lymphoma and a small group of idiopathic, spontaneous chylous pericardial effusion have also been reported as the causes. Here, we report a rare case of pericardial effusion secondary to chylous fistula in a 63-year-old man with Poland syndrome. The case highlights an unusual thoracic duct anomaly as a cause of our reported chylous pericardial effusion.
