Thymoma Presenting as Right-Side Heart Failure in a Healthy Patient: A Case Report

Thymoma is a rare tumor yet the most common neoplasm of the anterior mediastinum, accounting for 20-25% of all mediastinal tumors. Its incidence peaks in the fourth and fifth decades of life. Usually thymoma is diagnosed incidentally on chest imaging, or when investigating patients with myasthenia gravis, or with chest symptoms such as cough, chest pain, or dyspnea. We report here an unusual case of recidivant thymoma presenting with right heart failure in a 69 years old man.
