A multimodality imaging approach to multifocal intracardiac masses

The authors expose a case report of a 75-year-old woman admitted due to syncope and history of endometrial sarcoma. Echocardiography at hospital admission revealed two cardiac masses (in the right atrium [32x38 mm] and the other in the left ventricle [42x32 mm]), both with mobility and causing dynamic obstruction of the tricuspid valve and left ventricular outflow tract. Metastatic lesions were promptly suspected, considering the previous history, and an approach based on multimodality cardiovascular imaging was performed for differential diagnosis. Endometrial stromal sarcomas are rare tumors of the uterus corresponding to 0.2-1% of all uterine malignancies. Intracardiac metastasis from endometrial stromal sarcoma is a rare finding. The majority of reported metastasis is to the right side of the heart, being this case report a rare case of left chamber involvement.
