Figure

• 

  FIG. 1 T2-weighted (A, B), diffusion (C) and apparent diffusion coefficient (D) brain magnetic resonance imaging of the patient reveals acute infarctions in both cerebellums associated with the posteroinferior cellebellar artery (left dominant).

• 

  FIG. 2 Multiple transesophageal echocardiography image views at the midesophageal level (A, B). It was impossible to visualize the left atrial appendage in its typical location. Contrast-enhanced multidetector computed tomography with axial (C) and 3 dimensional volume-rendering (D) images. The left atrial appendage was not visualized. In contrast, the great cardiac vein and left circumflex coronary artery were clearly observed along with the atrioventricular groove. LA: left atrium, LV: left ventricle, LPV: left pulmonary vein, GCV: great cardiac vein, LCx: left circumflex coronary artery.
