A multimodality imaging approach is useful for accurately characterizing rare intracardiac masses such as calcified amorphous tumors and their complications.

Alerts clinicians to consider calcified amorphous tumors in right ventricular masses with embolism; leaves open optimal management strategies.
Cardiac calcified amorphous tumors (CATs) can arise in all four chambers of the heart. Cardiac CATs can cause diverse symptoms according to their locations, and mass or embolic effects. Pulmonary emboli arising from cardiac CATs have been reported, but the true incidence is unknown due to their rarity. Herein we report a rare case with diffuse CATs in the right ventricle which caused a calcific pulmonary embolism and right-sided heart failure. Echocardiography, chest non-contrast computed tomography, and cardiac magnetic resonance imaging helped us diagnose the CATs. We recommend the usefulness of a multimodality imaging approach to characterize intracardiac masses and their complications accurately.

Hyun et al. (2011) conducted a case report in Cardiac calcified amorphous tumor (CAT) with pulmonary embolism and right-sided heart failure (n=1). Multimodality imaging and empirical anticoagulation was evaluated. A rare case of a diffuse calcified amorphous tumor in the right ventricle caused calcific pulmonary embolism and right-sided heart failure in a 33-year-old man, diagnosed via multimodality imaging.
