Background: Ventricular thrombosis represents a not uncommon complication of Acute Myocardial Infarction (AMI) and Left Ventricular (LV) thrombosis may complicate large anterior ST-elevation myocardial infarction with anteroapical aneurysm. Right ventricular thrombosis is a more rare complication of inferior infarction. Transthoracic echocardiogram is routinely performed in patients with AMI to assess left ventricular function and the occurrence of thrombotic complications. However, other imaging techniques are occasionally required to more clearly evaluate thrombus extent and endocardial border line.

Methods: We report a case of biventricular thrombosis firstly found at echocardiograph examination; the exact extension of biventricular thrombosis, however, was more clearly defined at CT scan.

Results: In case of large ventricular thrombosis, CT scan may be useful in the exact definition of thrombus extension when cardiac magnetic resonance is not feasible.

Conclusion: When transthoracic ultrasonography does not allow adequate characterization of the thrombus and cardiac magnetic resonance is not feasible, CT scan can provide additional definition of cardiac walls and the extent of the thrombus.
