Uncommon etiology of right atrial tumour - extension of thyroid cancer

Abstract

Direct tumour extension into the right atrium in thyroid cancer is extremely uncommon. We report the case of an 80-year-old woman with echocardiography diagnosed in the right atrial mass. A large thyroid tumour with extension into the right jugular vein (JV), the superior vena cava (SVC) fi lling the right atrium was revealed by magnetic resonance imaging (MRI). Percutaneous fi ne-needle aspiration biopsy led to carcinoma being strongly suspected. The massive intravascular invasion and age of the patient contra-indicated surgical resection.
