[Intracavitary cardiac metastasis of osteosarcoma: echocardiographic aspects].

Osteosarcoma is a malignancy whose various sites of metastasis greatly modify its ultimate prognosis. In this study we present a case of a 15 years old girl affected by osteosarcoma of the left femur with cardiac metastasis in the right ventricular cavity. The echocardiogram made it possible the in vivo diagnosis. It is recommended that an echocardiographic study is performed routinely in patients affected by osteosarcoma.
