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 72-year-old female with chest tightness and bilateral lower extremity edema for over 3 days. The patient had no obvious pro-thrombosis 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 soft-tissue-like space-occupying lesion in the right atrium is encountered, especially with a ring-like calcification, thrombus should be considered as one of the differential diagnosis.
