We present a case of a 23-year-old man with previous history of a primary low grade myxofibrosarcoma of the left parietal-occipital convexity resected in March 1999. He subsequently underwent several interventions for multiple local recurrent disease until March 2004. At that time, complete remission was documented. About 8\u2005years later, in February 2012, the patient was admitted to the emergency room with refractory acute pulmonary oedema. On work up, sustained monomorphic ventricular tachycardia and hyperechoic myocardial mass with invasion of the right ventricular cavity were detected. Electrical cardioversion was unsuccessful and irreversible cardiac arrest followed. The autopsy confirmed multiple bilateral lung metastases, malignant pulmonary embolism and myocardial invasion by the primary tumour, with intracavitary cardiac thrombosis and absence of intracranial disease. To the best of our knowledge, this is the first report of extracranial metastases of this neoplasm.<\/jats:p>","DOI":"10.1136\/bcr-2015-214052","type":"journal-article","created":{"date-parts":[[2024,5,20]],"date-time":"2024-05-20T18:46:43Z","timestamp":1716230803000},"page":"bcr2015214052","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Right cardiac intracavitary metastases from a primary intracranial myxofibrosarcoma"],"prefix":"10.1136","volume":"2016","author":[{"given":"Diogo Alpuim","family":"Costa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pedro","family":"Barata","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emanuel","family":"Gouveia","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manuela","family":"Mafra","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2016,3,24]]},"reference":[{"key":"2025042703024161000_2016.mar24_1.bcr2015214052.1","first-page":"633","article-title":"Cardiac metastasis of melanoma as first manifestation of disease","volume":"5","author":"Pinho","year":"2009","journal-title":"Rev Port Cardiol"},{"key":"2025042703024161000_2016.mar24_1.bcr2015214052.2","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.21.2.g01mr15439"},{"key":"2025042703024161000_2016.mar24_1.bcr2015214052.3","doi-asserted-by":"crossref","first-page":"1662","DOI":"10.1200\/JCO.1986.4.11.1662","article-title":"Cardiac metastases from soft-tissue sarcomas","volume":"4","author":"Hallahan","year":"1986","journal-title":"J Clin Oncol"},{"key":"2025042703024161000_2016.mar24_1.bcr2015214052.4","first-page":"928","article-title":"Primary and metastatic cardiac sarcomas: a 12-year experience at a German heart center","volume":"5","author":"Agaimy","year":"2012","journal-title":"Int J Clin Exp Pathol"},{"key":"2025042703024161000_2016.mar24_1.bcr2015214052.5","doi-asserted-by":"publisher","DOI":"10.1093\/jjco\/hyq246"},{"key":"2025042703024161000_2016.mar24_1.bcr2015214052.6","first-page":"127","article-title":"Myxofibrosarcoma.
