ZYLBERMAN, Marcelo et al. Chylopericardium and bilateral chylothorax in a breast cancer patient. Medicina (B. Aires) [online]. 2014, vol.74, n.1, pp.62-63. ISSN 0025-7680.

Non traumatic chylopericar dium is mostly secondary to infection, congenital or neoplastic disease that invade mediastinal lymph nodes and modify the normal lymphatic flow. It is associated to chylothorax in approximately 3% of cases. We report the case of a 52 years old woman with diagnosis of advanced breast cancer. She was admitted with bilateral pleural effusion and echocardiographic signs of cardiac tamponade. A CT scan disclosed multiple mediastinal lymphadenopathy. The level of tryglicerides in pleural effusion was 372 mg/dl. A percutaneous pericardiocentesis was performed, obtaining chyle, with 984 mg/dl of tryglicerides and cholesterol 90 mg/dl levels. Treatment strategy was modified. We reviewed pathophysiology, diagnostic criteria and treatment of this rare entity.
