Take a look at the heart: Incidental detection of a right atrial thrombus during abdominal MR

Cardiac masses include a wide range of lesions whose nature could be both neoplastic (primary and secondary) or not. Here we report the case of a 53-year-old woman referred to our center for pancreatic lesion follow up by magnetic resonance. The collateral finding of a rounded-shaped lesion in the right heart atrium, during the abdomen examination, led to further diagnostic investigation. Cardiovascular magnetic resonance by nonparametric and parametric sequences was performed to settle the differential diagnosis, allowing for the definition of right atrial thrombus. At the best of our knowledge no data are available in literature about the incidental diagnosis of cardiac thrombi through abdominal magnetic resonance. This case underlines the importance of image evaluation for incidental findings, further demonstrating the feasibility of initiating an image-guided therapy after a characterization by CMR.
