Whole body FDG PET-CT 3.5% in general population and up to 9.1% in patients performed for staging of disease revealed intense FDG with known malignancies. Primary lung cancer is the uptake in the periphery of the primary lesion and most common cause (36-39%) of cardiac metastases, widespread metastasis (Figures 3A-D). An intense focus followed by breast cancer (10-12%) and hematologic of FDG uptake was also noted in a hypodense lesion in malignancies (10-21%). We report a case of myocardial the cardiac apex of the myocardium which was initially metastasis from lung cancer, which initially presented as
