Why the study?
Primary cardiac angiosarcoma typically metastasizes to the lungs, and bone metastases very rarely occur without concurrent pulmonary metastases.
Highlights a rare presentation of cardiac angiosarcoma with bone metastases but no pulmonary involvement, detectable by FDG PET/CT.
Alerts clinicians to possible bone metastases in cardiac angiosarcoma without lung lesions; hypothesis-generating for FDG PET/CT staging.
Primary cardiac angiosarcoma is rare and often advances by dissemination. Lungs are the most common metastatic sites, especially when the tumor originates in the right side of the heart. Bone metastases from cardiac angiosarcoma very rarely occur without concurrent pulmonary metastases. We report a case of cardiac angiosarcoma having prominent bone metastases without concurrent pulmonary lesions, as demonstrated by FDG PET/CT scan.
