Cardiac Metastasis of Breast Cancer: A Case Report

Breast cancer is one of the most common cancers in women. As we know, cardiac metastases occur rarely. In this study, a 40-year-old woman referred to the hospital due to severe pain in the right leg. She was diagnosed with deep vein thrombosis (DVT) and received treatment, but, after one month and a half she returned with severe pain, exacerbated shortness of breath, cramping pain, and chest pain. With the diagnosis of lung embolism, she received anticoagulant therapy and discharged after recovery. Then, about two months later, the patient was admitted for the third time, with symptoms of shortness of breath, chest pain, and right foot edema. In Doppler echocardiography, acute to chronic thrombosis was reported in femoral popliteal vein and common femoral vein with external liliac expansion. Based on the computed tomography angiography (CTA) and Echocardiography, the patient was diagnosed with pulmonary embolism with a mass in the right ventricular, so, cardiothoracic surgery consultation was done. During the operation, extensive spread of metastasis was seen on mediastinum, the aorta, and pericardial space. A biopsy was performed and metastatic breast cancer was reported. This study signifies the importance of examining patients with recurrent DVT for malignancy.
