An 83-year-old woman underwent transthoracic echocardiography (TTE) to assess her left ventricular systolic function. The TTE showed a large, round, echo-dense mass with central echo-lucencies resembling a posterior periannular tumor.
There was no associated mitral valvular dysfunction, and left ventricular function was good. Further assessment was performed using electrocardiographic-gated cardiac multislice computed tomography. This demonstrated that the mass seen on TTE was due to gross calcification of the posterior portion of …
