[Pulmonary embolism to the rescue in cardiac tamponade].

The association of cardiac tamponade and pulmonary embolism has not previously been described. We report the case of a patient, who presented with such an association, due to an underlying pulmonary carcinoma. When a major pericardial effusion is associated with pulmonary hypertension, some echocardiographic signs of tamponade may appear, such as a moderate right ventricular collapse, or the absence of a paradoxical septum. The presence of pulmonary hypertension in this context of tamponade may have paradoxically saved the life of this patient.
