Wavering calcified amorphous tumour of the heart in a haemodialysis patient

Takayuki Kawata et al. Interact Cardiovasc Thorac Surg. 2013 Feb.

Abstract

Calcified amorphous tumour is a rare, non-neoplastic, endocardially based, intracavitary cardiac mass. This report describes a 59-year old man in whom a mobile mass was found incidentally in the heart by routine echocardiography after he had been on haemodialysis for 3 years. Transoesophageal echocardiography revealed a high-echoic swinging tumour that originated from the annulus of the anterior commissure of the mitral valve. Surgical resection was performed to prevent embolization, and his clinical course was excellent.

Figure 1:
(A) Transthoracic echocardiogram. The long-axis view shows high-echoic mass (arrow) adhering to the mitral annulus of the anterior leaflet. (B) Transoesophageal echocardiogram. The short-axis view shows a cudgel-shaped, homogenous, high-echoic mass (arrow) that originated from the annulus of the anterior commissure of the mitral valve near the left fibrous trigone. Mitral annulus calcification was also recognized in the same area. LA: left atrium; LV: left ventricle; LAA: left atrial appendage.
