Magnetic resonance imaging findings in cardiac lipoma.

Journal of the Belgian Society of Radiology, 2012
Cardiac lipomas are exceedingly rare benign tumors of the heart. They are usually asymptomatic. Occasionally, they are found on MRI as an incidental finding. We report a case of a 68-year-old woman who presented with shortness of breath. Transoesophageal
