Case Roport: Pericardial tamponade and coexisting pulmonary embolism as first manifestation of non-advanced lung adenocarcinoma

Pericardial effusion and pulmonary embolism are relatively common complications of malignancy and are  uncommon as its initial manifestation. This report describes a case of a patient, who presented with this  association, due to an underlying pulmonary adenocarcinoma. When a major pericardial effusion is associated with pulmonary hypertension, some echocardiographic signs may redress the diagnosis. This case  emphasizes a challenge diagnostic which may be guided by high right ventricular pressure and on the other hand the importance of keeping both these conditions in mind when dealing with context of malignancy.Key words: Pericardial tamponade, pulmonary embolism, lung adenocarcinom
