Cardiac angiosarcoma with pulmonary and adrenal metastases diagnosed by FDG-PET/CT-guided adrenal biopsy

Primary cardiac angiosarcoma is a high-grade aggressive tumor with a poor prognosis and low incidence. We describe a case of cardiac angiosarcoma, with pulmonary and adrenal metastases, diagnosed via fluorodeoxyglucose-positron emission tomography/computed tomography-guided adrenal biopsy. Cardiac angiosarcoma should be considered in a patient with a cardiac mass with no tumor cells in the pericardial fluid. Fluorodeoxyglucose-positron emission tomography/computed tomography could be useful in determining the biopsy site.
