[Pericardial tamponade and carcinomatous lymphangitis as primary manifestation of lung neoplasm].

Cardiac tamponade (CT) and Carcinomatous lymphangitis (CL) association as an initial clinical presentation of a neoplasm is very uncommon, creating diagnosis difficulties in the patient first evaluation. This paper reports one case of a male who was admitted in Emergency Department with clinical and radiological findings of heart failure. Following studies showed CT and CL secondary to a bronchial adenocarcinoma. Differential diagnosis is really important for its associated therapeutic implications because of the CT hemodynamic worsening situation due to the diuretic and vasodilators used in the treatment of heart failure. An echocardiography should be done because it is very useful for the initial evaluation of a heart failure of obscure origin.
