The differential diagnosis for a cardiac mass includes primary and metastatic neoplasms. While primary cardiac tumors are rare, metastatic disease to the heart is a common finding in cancer patients. Several “tumor-like” processes can mimic a true cardiac neoplasm with accurate diagnosis critical at guiding appropriate management. We present a pictorial essay of the most common benign cardiac masses and “mass-like” lesions with an emphasis on magnetic resonance imaging features.Keywords: Benign neoplasms, cardiac, cardiac masses, magnetic resonance, magnetic resonance imaging
