Why the study?
Intramyocardial lipomas are rare benign cardiac tumors that often present a diagnostic dilemma because of nonspecific clinical and imaging features on initial evaluation.
Multimodality imaging, particularly CT and cardiac MRI, is essential for the accurate characterization of rare primary cardiac tumors such as intramyocardial lipomas when initial echocardiography is inconclusive.
May warrant CT/CMR after inconclusive echocardiography for cardiac masses; extends characterization of rare intramyocardial lipomas.
Intramyocardial lipomas are rare benign cardiac tumors that often present a diagnostic dilemma due to their nonspecific clinical and imaging features on initial evaluation. We report the case of a 40-year-old asymptomatic male who presented with a large intramyocardial lipoma arising from the basal inferior wall of the left ventricle. Initial transthoracic echocardiography revealed an echogenic mass in the region of the left ventricle basal septum but was insufficient for definite characterization. Cross-sectional imaging, including computed tomography (CT) and cardiac magnetic resonance imaging (MRI), demonstrated a homogeneous fat-density mass consistent with lipoma. This case highlights the pivotal role of multimodality imaging in accurately characterizing a rare primary cardiac tumor.
