    Abstract:
    The echocardiographic findings of an intramyocardial dissecting hematoma that formed after an extensive acute myocardial infarction of the anterior wall of a 42-year- old man are described. Serial transesophageal studies were used to construct 3-dimensional images that clarified the participation of various myocardial layers that surrounded the dissecting hematoma. The patient was successfully treated with intra-aortic balloon counterpulsation and subsequently coronary artery bypass grafting. Intramyocardial dissecting hematoma is a rare complication of acute infarction; differential diagnosis must be made with pseudoaneurysm by establishing integrity of epicardium and with intracavitary thrombosis by identifying the endomyocardial layer surrounding the neoformation and associated wall movement.
