We present a primary intramuscular vascular malformation of the left ventricle in an asymptomatic 12-year-old girl. Characteristics on cardiac magnetic resonance imaging, specifically increased signal intensity on T2-weighted images, and marked contrast enhancement with gadolinium were suggestive of increased vascularity. Histologically, the mass was determined to be an intramuscular vascular malformation of the small vessel arteriovenous subtype. This represents one of a select few intramuscular vascular malformations of the left ventricle reported in children. Our patient remains completely asymptomatic and has had no change in the size and appearance of the mass after more than 30 months of follow-up.<\/jats:p>","DOI":"10.1017\/s1047951113000346","type":"journal-article","created":{"date-parts":[[2013,5,22]],"date-time":"2013-05-22T04:58:03Z","timestamp":1369198683000},"page":"656-660","source":"Crossref","is-referenced-by-count":1,"title":["Intramuscular small vessel arteriovenous malformation of the left ventricle in an asymptomatic adolescent: a case report and literature review"],"prefix":"10.1017","volume":"23","author":[{"given":"Amy N.","family":"McCammond","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erin R.","family":"Rudzinski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian J.","family":"Morrison","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Silberbach","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2013,5,22]]},"reference":[{"key":"S1047951113000346_ref7","doi-asserted-by":"crossref","first-page":"1107","DOI":"10.1016\/S0002-8703(97)70032-2","article-title":"Pediatric primary benign cardiac tumors: a 15-year review","volume":"134","author":"Beghetti","year":"1997","journal-title":"Am Heart J"},{"key":"S1047951113000346_ref11","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.104.487645"},{"key":"S1047951113000346_ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2011.05.027"},{"key":"S1047951113000346_ref13","doi-asserted-by":"publisher","DOI":"10.1111\/j.1747-0803.2011.00526.x"},{"key":"S1047951113000346_ref6","doi-asserted-by":"publisher","DOI":"10.1007\/s00246-004-0717-2"},{"key":"S1047951113000346_ref12","doi-asserted-by":"publisher","DOI":"10.1016\/j.jflm.2008.08.020"},{"key":"S1047951113000346_ref1","first-page":"1255","article-title":"MRI imaging of cardiac tumors","volume":"25","author":"Sparrow","year":"2005","journal-title":"Radio Graphics"},{"key":"S1047951113000346_ref10","first-page":"1","article-title":"Surgical repair in neonatal life of cardiac hemangiomas diagnosed prenatally","volume":"15","author":"Sharma","year":"2009","journal-title":"Cardiol Young"},{"key":"S1047951113000346_ref14","doi-asserted-by":"publisher","DOI":"10.1111\/j.1601-0825.2010.01661.x"},{"key":"S1047951113000346_ref3","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMc0708819"},{"key":"S1047951113000346_ref8","doi-asserted-by":"publisher","DOI":"10.1007\/s00246-005-1017-1"},{"key":"S1047951113000346_ref9","doi-asserted-by":"publisher","DOI":"10.1272\/jnms.77.2"},{"key":"S1047951113000346_ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2009.04.025"},{"key":"S1047951113000346_ref4","doi-asserted-by":"publisher","DOI":"10.1097\/MOO.0b013e328332a4eb"}],"container-title":["Cardiology in the Young"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S1047951113000346","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,4,23]],"date-time":"2019-04-23T15:45:28Z","timestamp":1556034328000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S1047951113000346\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,5,22]]},"references-count":14,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2013,10]]}},"alternative-id":["S1047951113000346"],"URL":"https:\/\/doi.org\/10.1017\/s1047951113000346","relation":{},"ISSN":["1047-9511","1467-1107"],"issn-type":[{"value":"1047-9511","type":"print"},{"value":"1467-1107","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,5,22]]}}}
