Multiple Cortical Hypointense Lesions Revealed by T2*-Weighted Imaging and Micro-aneurysmal Lesions in a Case of Cardiac Myxoma

Multiple cortical hypointense lesions on T2*-weighted images and ischemic lesions are one of the radiological manifestations of cardiac myxoma, while the mechanism of the hypointense lesions is inconclusive. We describe a 60-year-old woman with a cardiac myxoma who presented with multiple ischemic lesions and cortical hypointense lesions revealed by T2*-weighted images. A gadolinium-enhanced T1-weighted image revealed micro-aneurysmal lesions, which corresponded to the hypointense lesions. Previous pathological studies have revealed that aneurysmal lesions could be caused by cardiac myxoma. Our findings suggest a potential association between cortical microbleeds and microaneurysmal changes in patients with cardiac myxoma.
