Abstract
A 27-year-old female with a history of acute lymphoblastic leukemia in remission presented with chest pain, liver cirrhosis, and a thrombus in the hepatic vein on ultrasound. Further workup with computed tomography (CT) and magnetic resonance imaging (MRI) revealed a mass extending from the inferior vena cava to the right atrium, 3.4 x 3.4 x 7.0 cm in size. She underwent excision of the intracardiac mass with a full sternotomy and cardiopulmonary bypass successfully. Her postoperative course was uncomplicated. She was discharged home on postoperative day six. Subsequent histopathology confirmed high-grade leiomyosarcoma. Postoperative positron emission tomography CT showed no evidence of metastatic disease.
