Cardiac Calcified Amorphous Tumor

A cardiac calcified amorphous tumor is a rare, non-neoplastic cardiac mass. Its cause, clinical findings, and treatment are still unknown. It was first described in 1997 as a non-neoplastic mass characterized by a pedicle and diffuse calcifications by Reynolds et al. Characteristic histologic features such as the presence of calcified nodules in an amorphous background of fibrin with degeneration and focal inflammation allow an accurate diagnosis of cardiac CAT. The pathogenesis of cardiac CAT has been linked to organized thrombi, but its precise etiology is unknown
