Multimodality imaging of a rare LV mass in an asymptomatic Patient

Abstract

Cardiac imaging plays an important role in detection and differential diagnosis of cardiac masses. We report a 43-year-old male presented with palpitations. Clinical examination, ECG and chest x-ray were unremarkable. Trans-thoracic echocardiography showed a well-defined, large left ventricular mass at the anterolateral papillary muscle with multiple chordal insertion into the mass. Cardiac computed tomography showed heterogenous contrast enhancement. Cardiac magnetic resonance imaging showed high signal intensity, and early heterogeneous enhancement hyperintense on T2, with regional variations in vascularity, as well as late gadolinium enhancement. Post-surgical excision pathological examination confirmed cardiac hamartoma.
