INTRODUCTION: Myxoid liposarcoma rarely metastasizes to the heart. Therefore, diagnosing cardiac metastases of myxoid liposarcoma is challenging, and treatment is often ineffective. Here, we report a case of cardiac metastasis from a myxoid liposarcoma detected using whole-body MRI, which was successfully treated with a multidisciplinary approach, including surgery, resulting in favorable outcomes.
CASE PRESENTATION: A 61-year-old woman had a history of pelvic myxoid liposarcoma, which was diagnosed and surgically resected at the age of 47. During follow-up, cardiac metastases were identified using whole-body MRI. The patient underwent tumor resection involving the free wall of the left ventricular apex using a cardiopulmonary bypass. The tumor had invaded the ventricular septum, creating a left-to-right shunt due to a fissure in the tumor. This necessitated a double-patch reconstruction following tumor resection. Postoperative radiation therapy was administered as adjuvant treatment. Five years after treatment, there has been no recurrence of the myocardial myxoid-type liposarcoma.
CONCLUSIONS: Complete resection of cardiac metastatic lesions from myxoid liposarcoma was achieved, resulting in favorable outcomes. Early detection of localized cardiac metastases using MRI may enable aggressive surgical interventions.
