Intracardiac Thrombus Case Caused by Blunt Trauma Due to Child Abuse

Abstract

Intracardiac thrombus is a rare condition in children, although there has recently been an increase in case reports in the literature. We here report an asymptomatic intracardiac thrombus caused by blunt trauma due to child abuse in a 4-year-old girl. On the echocardiogram, one can see pericardial fluid surrounding all of the heart, and a mobile mass, a thrombus of 5.8 x 9 mm in diameter, was observed in the right atrium and on the free border of the tricuspid valve. The thrombus and pericardial fluid disappeared on the follow-up echocardiogram performed after the 10-day heparin therapy.
