Evaluation of causal heart diseases in cardioembolic stroke by cardiac computed tomography

Figure 2 Left atrial appendage thrombus. An 85-year-old woman with congestive heart failure and atrial fibrillation underwent cardiac computed tomography (CCT) in search of underlying heart disease. She suffered from acute ischemic stroke three months after CCT. A and B: Early phase CCT images (A: Axial; B: Sagittal) show multiple filling defects in left atrial appendage (LAA, arrow and arrowheads); C and D: Delayed phase CCT images (C: Axial; D: Sagittal) also show multiple filling defects in LAA (arrow and arrowheads) confirming multiple LAA thrombus; E: Diffusion-weighted brain magnetic resonance imaging shows hyperintense lesions in right temporoparietal lobe and left anterior limb of internal capsule (arrows).
