Intracardiac Thymoma with Superior Vena Cava and Left Brachiocephalic Vein Extension: A Case Report

Abstract

Thymomas are common anterior mediastinal tumors with a relatively favorable prognosis compared to that of other types of thoracic malignancies. However, thymomas that invade surrounding structures, such as the heart or vena cava, have been infrequently reported, and intracardiac thymomas are exceedingly rare. Treatment of invasive thymoma is difficult because the high rate of incomplete resection results in a high rate of recurrence. Herein, we present a rare case of a thymoma that originated in the right atrium and extended into the superior vena cava and brachiocephalic vein.
