Angiosarcoma in the right atria demonstrated by fusion images of multislice computed tomography and positron emission tomography using F-18 Fluoro-Deoxyglucose.

Primary cardiac tumors are rare. In this report, using fusion images of multislice computed tomography (MSCT) and positron emission tomography (PET) using F-18 Fluoro-Deoxyglucose, we could diagnose, morphologically, the location, size and extent of the tumor, and degree of blood flow from the feeding artery (by MSCT) and establish that this cardiac tumor was malignant (by PET) before surgical operation. Histologically, the tumor was diagnosed as a cardiac angiosarcoma.
