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.
