Abstract
Chylotamponade involves rapid accumulation of chyle in the pericardium elevating the pericardial pressures above normal right heart filling pressures, and is extremely rare. A 12-y-old boy presented to the emergency with complaints of facial puffiness for 1 mo and breathing difficulty for 1 wk. The neck veins were distended, and the heart sounds were muffled. A chest CT demonstrated a large anterior mediastinal mass with pleural and pericardial effusions. Echocardiography confirmed cardiac tamponade. Pericardiocentesis revealed chylopericardium. He was placed on a chyle leak diet, and the drain was removed after 48 h. Biopsy of the mediastinal mass revealed a primary mediastinal B-cell lymphoma. He was successfully managed with chemotherapy. The index case demonstrates how prompt identification and management of chylotamponade and treatment of the underlying cause can lead to good clinical outcomes.
