Workup for the patient's presenting stroke on this admission revealed that the pleural-based mass in the right upper lobe had significantly increased in size, and that this tumor now extended from the right upper lobe into the chest wall via the right superior pulmonary vein into the left atrium, across the mitral valve, and into the left ventricle (Figure 1A and B).
(A) The cardiac myxoid tumor resected via a left atriotomy (patient's head is
on the left side of the figure). Blue arrow marks the myxoid tumor on the
mitral valve. (B) Gross image of the excised cardiac myxoid tumor.
