Benign Metastasizing Leiomyoma Presenting as a Right Ventricular Mass.

ABSTRACT:

Background

Masses in the right ventricle are uncommon, but if present, they are most often attributed to either primary cardiac tumors or metastatic disease.

Case summary

A 50-year-old woman presented with progressive lower extremity edema and was diagnosed with a right ventricular mass causing severe tricuspid insufficiency and near-total obstruction of the pulmonary artery.
