“…Cardiac metastasis occurs more frequently than primary tumors; however, endocardial involvement of the right atrium is particularly rare, but it may be seen with aggressive lymphoma and hepatocellular carcinoma. Estimated rates of right atrial involvement following metastatic breast cancer diagnosis remain unknown, with a limited number of documented case reports [3][4][5]. It is proposed that metastasis occurs via a hematogenous spread using the azygous venous system, which provides transvenous drainage of the breasts, particularly the right breast, to the superior vena cava and cardiac chambers [7].…”

“…An estimated 15% of all patients with metastatic cancer have cardiac involvement with the pericardium acknowledged as the most common site of metastasis due to malignant lymphatic invasion [1]. Endocardial involvement is exceedingly rare, occurring in less than 5% of all cardiac metastases [2], particularly among breast cancer where estimates are unknown, with a limited number of documented case reports [3][4][5]. Endocardial masses of the right atrium may result in signs of right heart failure, such as chest pain, dyspnea, elevated jugular venous pressure, body swelling, and pulmonary tumor emboli.…”

We present the case of a 42-year-old female with a history of human epidermal growth factor 2 (HER2) receptor-positive breast cancer status post bilateral mastectomy with metastasis to the spine and to the brain, who underwent transesophageal echocardiography (TEE) after outpatient transthoracic echocardiography (TTE) was suggestive of right atrial thrombus in transit. TEE revealed an atrial mass with a pedunculated stalk attached to the inferior right atrium near the inferior vena cava with a necrotic center. These findings were suggestive of an endocardial metastatic mass secondary to her primary breast cancer. The pericardium is the most common site of cardiac metastasis; meanwhile, endocardial involvement is infrequent, occurring in less than 5% of all cardiac metastases. Right atrial masses may cause evidence of right heart failure and thromboembolism of the pulmonary arteries. Treatment focuses on targeted chemotherapy, radiation therapy, and interventions as indicated. In this case, following the diagnosis of a right atrial mass, the patient was discharged the same day to begin outpatient chemotherapy.

“…This information may prove valuable during differential diagnosis, as it shows greater than expected SCT incidence in selected groups of patients. The data from literature show SCTs occurring even long after the initial cancer diagnosis and treatment (more than 20 years), either after confirmed cancer relapse or as a first sign of cancer recurrence [7,12,13]. Confirmed metastases in other territories raises the likelihood of SCTs from 9% to 18%, according to available data [7].…”

The Role of Multimodality Imaging in the Diagnosis and Follow-Up of Malignant Primary Cardiac Tumors: Myxofibrosarcoma—A Case Report and Literature Review

et al. 2023

Cardiac tumors are a very rare but heterogenous group of diseases that may reveal themselves through a variety of nonspecific cardiac symptoms that may pose a challenge to the diagnostic process. Myxofibrosarcoma is a particularly rare type of cardiac tumor that carries a poor prognosis, thus making accurate and timely diagnosis essential. A 61-year-old woman presented with fatigue and shortness of breath during mild exercise, symptoms that have progressively worsened during the previous year. Multimodality imaging consisting of transthoracic and transesophageal echocardiography (TTE and TEE), cardiac magnetic resonance (CMR), cardiac computer tomography (CCT), and fluorodeoxyglucose positron emission computer tomography (18F-FDG PET-CT) was used for the diagnosis and postoperative follow-up of a myxofibrosarcoma.
