FDG-PET proves to be reliable in the diagnostic workup of a rare cardiac hemangioma.

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.
