Asymptomatic metastatic osteosarcoma to the right ventricle: Case report and review of the literature

Metastatic cardiac tumors are far more common than primary tumors, and benign primary cardiac tumors are common than malignant tumors. We report a 22-year-old Saudi woman with right femur osteosarcoma who was found to have a large right ventricular mass by transthoracic and transesophageal echocardiography. Diagnosis was highly suggestive by cardiac magnetic resonance imaging (MRI) and fluorodeoxyglucose positron emission tomography/ computed tomography (FDG PET/CT) scan. We performed a review of the literature for metastatic osteosarcoma of the right ventricle
