A calcified amorphous tumor (CAT) is a rare intracardiac mass that carries a risk of embolism. We herein present the case of a club-shaped CAT that originated from the calcified mitral annulus. Echocardiography indicated a pendular motion of the mass and repeated entrapment by a stenotic aortic valve that was sustained for several beats, mimicking a chameleon’s tongue. An emergency operation was performed because of the risk of embolism, as well as potential progression of cardiac failure due to worsening aortic valve stenosis. The histological findings were consistent with the diagnosis of a CAT. This report describes a case of an intracardiac tumor that showed unique motion like a chameleon’s tongue.
