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

Figure 11  Gradually increased atrial myxoma. An 80-year-old man with chest pain underwent cardiac computed tomography (CCT) to evaluate obstructive coronary artery disease. CCT showed severe stenosis in the left anterior descending coronary artery, and percutaneous coronary intervention was performed. Simultaneously, CCT incidentally demonstrated a left atrial mass that could not be visualized on transthoracic echocardiography. A: Axial (upper) and horizontal long axis (lower) reformatted CCT images show left atrial mass of 7 mm by 5 mm in diameter attached to interatrial septum (arrows); B: Axial (upper) and horizontal long axis (lower) reformatted CCT images performed one year later show increased mass size of 11 mm by 11 mm in diameter. Subsequently, elective surgical mass resection was performed. Histological examination confirmed cardiac myxoma.
