[Malignant non-Hodgkin's lymphoma presenting with cardiac tamponade]. / Tamponnade cardiaque révélatrice d'un lymphome malin non hodgkinien.

Malignant non-Hodgkin's lymphoma rarely involves the heart. However, all cardiac structures may be invaded, although the myocardium and pericardium are affected more often than the valvular structures. Diagnosis is important because treatment must be adapted. The cardiac signs are usually non-specific and lymphomas presenting in this way have only occasionally been reported. The authors report two cases in which malignant non-Hodgkin's lymphoma presented with cardiac tamponade.

[Hydatic disease of the heart presenting with pericardial effusion. A case report]. / Epanchement péricardique révélateur d'une hydatidose médiastinale. A propos d'un cas.

The authors report a rare case of multiple mediastinal hydatid cysts which ruptured in a 48 year old man who presented with a pericardial effusion. The diagnosis was confirmed by 2D echocardiography, completed by CT scan and magnetic resonance imaging. The patient was operated as a semi-emergency and the outcome was good. This case underlines the rare pericardial involvement and the severity of the complications of cardiac hydatid disease.
