Successful resection of a huge metastatic liposarcoma in the pericardium resulting in improvement of diastolic heart failure: a case report

Although liposarcoma often metastasizes to various organs, cardiac metastasis, including to the pericardium, is rare. We present a case of a third recurrence of pericardial metastasis from the thigh, which required surgical resection because of cardiac failure. Surgery was effective for improving cardiac function and reintroducing chemotherapy. This is the first reported case of metastatic pericardial liposarcoma, which was successfully resected three times. We believe that aggressive surgical treatment, when it can resolve cardiac impairment, potentially leads to a more favorable prognosis.
