Complete Resection of Cardiac Metastasis Myxoid Liposarcoma.

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.
