[Pericarditis with pericardial tumor-like manifestations in echocardiographic and magnetic resonance examinations].

: A case of acute cardiac insufficiency in a 26 year old woman is described. Ultrasound examination of the pericardium was suspect for an pericardial tumor with pericardial effusion and solid masses of tumor in the fluid. Magnetic resonance imaging (MRI) gave the impression of tumor in the pericardium. Pericardiocentesis showed neither malignant cells nor growth of microorganisms. The patient recovered completely on steroid therapy and control MRI showed anatomic normalisation of the cardiac region. It is concluded that idiopatic peracarditis can mimic pericardial tumor on ultrasound and MRI investigation.
