Myocardial abscess resulting in a pseudoaneurysm: case report.

This report describes the diagnostic workup of a case of a pseudoaneurysm of the heart resulting from Staphylococcal pericarditis and/or abscesses of the myocardium. The pericardial effusion and myocardial abscesses were detected on 2D echocardiography and computed tomography. The resulting pseudoaneurysm could be demonstrated on magnetic resonance imaging and color Doppler ultrasound, and confirmed by left ventriculography. Color-encoded Doppler ultrasound alone would have provided the definitive diagnosis of the aneurysm.
