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.
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.
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.
黏液样脂肪肉瘤很少转移至心脏。因此，诊断黏液样脂肪肉瘤的心脏转移具有挑战性，且治疗往往无效。在此，我们报告一例通过全身MRI检测到的黏液样脂肪肉瘤心脏转移病例，该病例采用包括手术在内的多学科方法成功治疗，取得了良好的效果。
一名61岁女性有盆腔黏液样脂肪肉瘤病史，47岁时被诊断并接受手术切除。在随访期间，通过全身MRI发现了心脏转移。患者在体外循环下接受了涉及左心室心尖游离壁的肿瘤切除术。肿瘤侵犯了室间隔，由于肿瘤内的裂隙导致了左向右分流。这使得在肿瘤切除后需要进行双层补片重建。术后给予放射治疗作为辅助治疗。治疗五年后，心肌黏液样型脂肪肉瘤未复发。
成功实现了黏液样脂肪肉瘤心脏转移病灶的完全切除，取得了良好的效果。使用MRI早期检测局限性心脏转移可能有助于积极的手术干预。
