18FDG-PET/CT imaging is a useful modality for evaluating the malignant nature of complex intracardiac masses such as rhabdomyosarcoma.
PET/CT may aid malignant cardiac mass characterization; leaves open prospective validation for rhabdomyosarcoma management.
We present the case of an adult male who arrived to our emergency room with progressive dyspnea that had been ongoing for 2 months. During the radiological investigation, we found a large intracardiac mass, which invaded the pericardium, pulmonary trunk, pulmonary arteries, and left ventricle. Studies done with the 18FDG-PET/CT scan helped us to determine the malignant nature of the mass and to suspect the diagnosis of rhabdomyosarcoma.
