1 Palpitations and a Left Ventricular Mass: An Odd Presentation of Left Dominant Arrhythmogenic Cardiomyopathy  Sandor Toledo, BA, Elizabeth Grigoryan, BA, Jacobo Kirsch, MD, Edward B. Savage, MD  The Annals of Thoracic Surgery  Volume 103, Issue 4, Pages e327-e329 (April 2017) DOI: /j.athoracsur Copyright © 2017 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 (A) Horizontal long axis and (B) parasagittal longitudinal long axis echocardiographic views reveal a hyperechoic mass centered about the inferolateral apical segments of the left ventricle (white arrows).

3 Fig 2 (A) Four-chamber magnetic resonance imaging (MRI) half-Fourier acquisition single shot turbo spin-echo sequence reveals a high-signal-intensity mass at the apical lateral myocardium with poorly defined posterior margins. (B) Four-chamber MRI phase sensitive inversion recovery (PSIR) sequence after intravenous administration of contrast shows striated patchy areas of late persistent enhancement within the mass. (C) Four-chamber view multiplanar reconstruction of the computed tomographic (CT) examination with contrast demonstrates again a very low-attenuation mass (fat attenuation) with poorly defined posterior margins. (D) Positron emission tomography–CT examination shows no abnormally increased metabolic activity associated with the cardiac mass (arrow heads).

4 Fig 3 Histology Images: (A) 4× and (B) 10× images demonstrate extensive infiltration of the myocardial perimysial space by mature adipocytes with no evidence of capsule formation.
