Abstract

Cardiac papillary fibroelastomas (CPF) are benign cardiac tumors and usually discovered incidentally during echocardiography. This report describes the case of a 68-year-old man, referred to cardiology for multiple masses of the left ventricle and left atrium. The transthoracic echocardiography revealed multiple oscillating masses in the left ventricle and aortic valve, non-mobile mass in the left atrium with severe mitral stenosis and moderate aortic regurgitation. The patient underwent surgical resection of the masses with valve replacements. Histopathologic examination confirmed the diagnosis of CPF in the left ventricle and aortic valve, thrombus in the left atrium.

Figure

  • Fig. 1 Small oval shaped masses seen in parasternal long axis view (A, arrows), parasternal short axis view (B, arrows), showing heterogeneous echogeneicity with some internal echolucency.

  • Fig. 2 Cardiac magnetic resonance imaging demonstrated non-enhanced masses in left atrium (A, arrow) between the orifice of the right superior and inferior pulmonary vein, and in left ventricle (B, arrow) showing heterogeneous signal intensity in T2 image.

  • Fig. 3 Gross specimen of 1:1 paraffin block (H&E stain, × 10) (A) reveals central stalk with papillary projection. Histological examination of the resected tumor showing papillary projection. The tumor surface is covered by a single layer of endocardial cells with an overlying thin layer of an underlying acellular stroma composed of elastic fibers and collagen (H&E stain, × 40) (B).
