An Intracardiac Accessory Thyroid Gland

Published:February 01, 2006DOI:https://doi.org/10.1016/j.amjcard.2005.10.029
      This report describes a 62-year-old woman with a history of pulmonary embolism who presented with a right ventricular cardiac mass that proved histologically to be normal thyroid tissue.
