Moving right atrial mass associated with hepatoma. Two cases detected by echocardiography.
Hepatoma with right atrial (RA) metastasis is rare, and to our knowledge, the echocardiographic description of a RA mass associated with hepatoma has never been described. Herein we report two cases of hepatoma, whose two-dimensional echocardiograms demonstrated a RA mass protruding into right ventricle during diastole, mimicking RA myxoma. However, in contrast to RA myxoma, these RA masses could be traced to the inferior venae cavae, which were dilated and filled with tumor echoes. Since prompt diagnosis and removal of these RA masses might prevent sudden cardiac death, we advocate performing echocardiographic examination in patients with hepatoma, who have cardiac symptoms or signs.
