High 18F-fluorodeoxyglucose uptake in cardiac tumor: A case report
1Department of Nuclear Medicine, the First Affiliated Hospital of Chongqing Medical University, Chongqing, China.
Background:
Cardiac tumors, especially malignant, are rare but aggressive tumors that mostly arise from the mesenchymal cells and represent a challenging diagnosis for clinicians. Recently, fluorine-18-fluorodiography positron emission tomography and computed tomography (F-FDG PET/CT) is an increasingly popular new technique with diagnosis of tumor.
Methods:
We report a case of a right heart tumor showing intense uptake of F-fluorodeoxyglucose (F-FDG) on position emission tomography/computed tomography (PET/CT) imaging. We discuss the clinical course and diagnostic evaluations.
Results:
The maximal standardized uptake values (SUVmax) for the cardiac and metastatic lesion were 17.2 and 12.9, respectively.
Conclusion:
F-FDG PET/CT imaging, which enables both morphological characterization and visualization of tumor metabolism, may be an effective and feasible noninvasive method for the diagnosis of malignant cardiac tumors.
