INTRODUCTION
Calcified amorphous tumor (CAT) of the heart is a non-neoplastic mass, has been characterized by nodules of calcium on a background of amorphous fibrinous material. Mitral annular calcification (MAC) is one of the most frequently associated conditions with CAT. Most of MAC-related CAT cases are reported in end-stage renal disease (ESRD) patients. We present a patient with normal renal function who was incidentally diagnosed with CAT arising from MAC.
Case presentation: An asymptomatic 43-year old man with normal renal function underwent echocardiography. Echocardiography revealed a highly mobile hyperechoic mass attached to the atrial side of mitral annulus superimposed on a heavily calcified mitral annulus. Cardiac surgery and histopathologic evaluation confirmed MAC-related CAT diagnosis.
Discussion and conclusion: MAC-related CAT is usually associated with ESRD patients. Precise etiology and management strategy of this benign tumor is remaining unclear. Rare incidence of this tumor in patients with normal renal function highlights the importance of further researches on the pathology of this uncommon condition.
