Figure 1:
A) Axial T2-weighted MRI demonstrates a solid and cystic optic pathway mass (black asterisk) in a 3-year-old boy
B) Axial diffusion-weighted MRI reveals restricted diffusion of the left posterior quadrant (white arrowheads) consistent with acute ischemia
C) 3D time-of-flight MR angiographic image at that time was normal
Figure 2: A) Apical 4-chamber view of echocardiogram demonstrates two apical, mural thrombi (white arrows); LA: left atrium, LV: left ventricle, RA: right atrium, RV: right ventricle
B) Parasternal short-axis view of echocardiogram demonstrates normal LV dimension with a small to moderate pericardial effusion (white dashed outline); RA: right atrium, RV: right ventricle
