FDG PET/CT can be a valuable imaging modality for characterizing cardiac neoplasms and detecting distant metastases in rare cases like primary cardiac angiosarcoma.
FDG PET/CT may aid cardiac mass evaluation in adolescents; leaves open prospective validation for benign versus malignant differentiation.
We present a case of an adolescent girl with a cardiac mass which was characterized as malignant on FDG PET/CT. In addition, FDG PET/CT revealed multiple hypermetabolic pulmonary lesions. The final diagnosis was primary cardiac angiosarcoma with pulmonary metastases, a rare malignancy especially in female patients at this age group. We emphasize the potential role of FDG PET/CT in patients with a cardiac neoplasm and present a literature review of FDG uptake in benign versus malignant cardiac tumors.
