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

Figure 10  Atrial myxoma. A 76-year-old man hospitalized with acute ischemic stroke underwent cardiac computed tomography (CCT) to further evaluate a left atrial mass observed on transthoracic echocardiography. A: Diffusion-weighted brain magnetic resonance imaging shows hyperintense lesions in bilateral cerebellar hemisphere, pons, splenium of corpus callosum, and bilateral occipital lobe (arrows); B–D: Axial (B), horizontal long axis (C), and short axis (D) reformatted CCT images show a 31-mm-sized lobulated left atrial mass attached to the interatrial septum (arrows). He had a previous history of chronic aortic dissection (asterisk). Urgent surgical mass resection was performed. Histological examination confirmed cardiac myxoma.
