Abstract: Myxoid liposarcoma (MLS) is a common subtype of liposarcoma in children, adolescents and young adults and can occur anywhere in the body, mostly in the deeper tissues of the extremities, especially the thighs. MLS has an unusual propensity for extrapulmonary metastases, and reviewing the literature, cardiac metastases from MLS are very rare, even in patients with advanced disease. We report a rare case of postoperative recurrence of MLS in the left thigh with ectopic and metachronous pericardial metastases. He was found to have a cardiac abnormality that was initially thought to be a pericardial cyst, but was later pathologically confirmed to be MLS metastasis. Cardiac metastases from MLS are rare, the prognosis is poor, and long-term follow-up of patients after discharge is necessary. CMR is useful to clarify the diagnosis of cardiac metastases, to define the anatomical relationship between the metastases and cardiac tissue and to determine myocardial activity and whether the myocardium is invaded.
