A Rare Cause of Left Atrial Mass

Figures

• 

  Figure 1. TTE, parasternal long-axis view, showing the mass attached to the posterior wall of the left atrium.

• 

  Figure 2. TTE, apical 4C zoom view focusing on the mass attached to lateral wall of the left atrium.

• 

  Figure 3. TEE revealed a left atrial mass (white arrows) arising from or next to the left lateral ridge. LA, Left atrium.

• 

  Figure 4. 3D Transesophageal echocardiogram image of the mass showing the mass arising from the lateral wall of the LA and extending above the mitral valve (MV).

• 

  Figure 5. CMR performed using a balanced steady-state gradient echo sequence showed a broad-based left atrial mass (white arrow). LA, Left atrium; LV, left ventricle.

• 

  Figure 6. CMR performed using an inversion recovery gradient echo sequence (late gadolinium enhancement) suggested that the mass (black arrow) was not a lipoma. LA, Left atrium; LV, left ventricle.

  Figure 7. LA mass specimen biopsy (hematoxylin and eosin staining, magnification 200×) showing principally red blood cells and platelets enmeshed in fibrin strands. The rare blue dots are leukocytes.
