Key result
A rare spherical mass in the right atrium, initially misdiagnosed as a myxoma by imaging, was definitively diagnosed as a thrombus following surgical resection and histopathological analysis.
Why the study?
Spherical thrombi in the right atrium are exceedingly rare, and conventional imaging modalities like TEE and CMR can misdiagnose them as myxomas.
Population
One 59-year-old male with an incidental spherical right atrial mass

Rare spherical right atrial thrombi warrant inclusion in intracardiac mass differentials; leaves open need for standardized multimodality imaging protocols.

A rare spherical right atrial thrombus can mimic a myxoma on conventional imaging, highlighting the need for multimodality imaging and clinical scoring systems like PLACE-T for accurate diagnosis.
Wu et al. (2025) conducted a case report in Right atrial spherical mass (thrombus) (n=1). Surgical resection and histopathological analysis was evaluated on Histopathological diagnosis. A rare spherical mass in the right atrium, initially misdiagnosed as a myxoma by imaging, was definitively diagnosed as a thrombus following surgical resection and histopathological analysis.
