Abstract :
Cardiac metastases of malignant tumors occur more frequently than primary tumors of the heart. Local invasion of the pericardium and heart is commonly seen in primary lung cancer, but myocardial metastasis without local invasion rarely occurs. 18-F fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) is widely used in the diagnostic evaluation and staging of different malignant tumors, but the FDG uptake of myocardium is intense and heterogeneous. A-55-year old male smoker was diagnosed with small cell lung cancer (SCLC) by bronchoscopic biopsy, and FDG PET/CT showed high FDG uptake in myocardium. Transthoracic echocardiagraphy revealed mass like lesions in the apical regions of both ventricules. After systematic evaluation of imaging studies, the mass was diagnosed as intracardiac metastasis of SCLC and histopathologic examination. This case shows that intracardiac metastases of malignant tumors can be seen without local invasion, and FDG PET/CT can be a useful diagnostic tool in evaluation of intracardiac metastasis
