Calcified Ball Thrombus in the Right Atrium: A Case Report

Thrombus in the right atrium is an extremely rare manifestation. Here we report a case of calcified ball thrombus in the right atrium in a 72yearold female with chest tightness and bilateral lower extremity edema for over 3 days. The patient had no obvious prothrombosis risk factors. Multimodality imaging examination depicted an oval soft tissue mass in the right atrium. Histopathological examination confirmed that to be a thrombus in the right atrium. To conclude, when a softtissuelike spaceoccupying lesion in the right atrium is encountered, especially with a ringlike calcification, thrombus should be considered as one of the differential diagnosis.
