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

Figure 3 Bilateral atrial thrombus. A 53-year-old man with atrial fibrillation and right renal infarction underwent cardiac computed tomography (CCT) in search of causal heart pathology of cardioembolism. A: Axial early phase CCT image shows filling defect in left atrial appendage (LAA, upper, asterisk). Axial delayed phase CCT image also shows filling defect in LAA confirming LAA thrombus (lower, arrow); B: Axial early phase CCT image shows filling defect in right atrial appendage (RAA, upper, asterisk). Axial delayed phase CCT image also shows filling defect in RAA confirming RAA thrombus (lower, arrowhead); C: Early phase CCT images (upper: Axial; lower: Sagittal) show filling defect in LA posterior wall, which suggests LA thrombus (black arrow).
