The noninvasive characterization of cardiac tumors is of clinical importance for surgical resection planning. Conventional radiological examinations like cardiac computed tomography (CT) or magnetic resonance imaging (MRI) may be misleading as benign cardiac lesions can present features suspicious for malignancy. Moreover, the low prevalence of cardiac tumors may additionally hamper a sound diagnosis. However, fluorodeoxyglucose-positron emission tomography (FDG-PET) has proven to be a reliable tool for cardiac tumor characterization. Here, FDG-PET/CT imaging of a 50-year-old man suffering from a cardiac tumor is presented. Despite CT and MRI signs of malignancy, FDG-PET characterized the tumor as benign. Histology confirmed the FDG-PET prediction and revealed a pericardial capillary hemangioma. Thereby, it seems important to integrate FDG-PET in the diagnostic workup of cardiac tumors.
心脏肿瘤的无创性特征对于手术切除规划具有临床重要性。传统的放射学检查，如心脏计算机断层扫描（CT）或磁共振成像（MRI），可能会产生误导，因为良性心脏病变可能呈现出疑似恶性肿瘤的特征。此外，心脏肿瘤的低发病率可能会进一步妨碍准确的诊断。然而，氟脱氧葡萄糖正电子发射断层扫描（FDG-PET）已被证明是一种用于心脏肿瘤特征描述的可靠工具。在此，展示了一名患有心脏肿瘤的50岁男性的FDG-PET/CT成像。尽管CT和MRI显示有恶性迹象，但FDG-PET将该肿瘤判定为良性。组织学检查证实了FDG-PET的预测结果，并显示为心包毛细血管瘤。因此，将FDG-PET纳入心脏肿瘤的诊断检查似乎很重要。
