Cardiac Masses and Where to Find Them

Cardiac masses pose a significant diagnostic challenge, requiring a structured imaging-based approach. Echocardiography represents the first-line and most essential diagnostic tool, providing a rapid, non-invasive, and cost-effective method for detecting and characterizing intracardiac lesions. While metastatic involvement is the most frequent cause of secondary cardiac masses, the primary tumors are predominantly benign. However, distinguishing between tumors, thrombi, and pseudotumors often necessitates advanced imaging techniques, such as cardiac magnetic resonance imaging (MRI) or computed tomography (CT). Meanwhile, in addition to the diagnostic role, imaging techniques are essential for risk stratification and guiding therapeutic decisions. Thus, a multidisciplinary approach integrating multiple imaging modalities is crucial for optimizing patient management and improving outcomes.
