A Case of Uterine Leiomyomatosis Extending into the Right Heart with an Unusual Echocardiographic Appearance.

Intravenous extension of uterine leiomyomatosis is a rare condition characterized by tumor invasion of the venous system and propagation toward the large abdominal veins. A few cases with extension to the right atrium have been reported, and the echocardiographic appearance of this entity is well described. The case we herein report is of interest because of its unusual echocardiographic findings.
