A cardiac pseudo-tumor associated with pseudo-infarction electrocardiographic pattern.
The electrocardiographic presentation of Q waves is an important diagnostic indication of myocardial infarction and other differential diagnoses. We report a case in which the electrocardiography revealed significant Q waves in V1 to V4. In addition, echocardiography disclosed an encapsulated mass lesion over the interventricular septum. Rather than confirm a cardiac tumor, magnetic resonance imaging disclosed hypertrophy of the myocardium with the ventricular septum showing prominent thickness > 3 cm. Hypertrophic cardiomyopathy was diagnosed. Cardiac pseudo-tumor with a pseudo-infarction electrocardiography pattern can be a rare presentation of hypertrophic cardiomyopathy.
