The Anterior (pre-visceral) Mediastinum

In this presentation, Dr. Constantine Raptis discusses the anterior (pre-visceral) mediastinum. He defines its boundaries and highlights its normal structures, including the thymus, fat, lymph nodes, and the left brachiocephalic vein. Dr. Raptis focuses on teaching with the "Ts" (teratomas, thymomas, terrible lymphomas, and thyroid goiters) and emphasizes the importance of management. He presents cases ranging from mature teratomas in young patients to lymphomas and thymic carcinomas in older individuals. Dr. Raptis underscores the significance of considering clinical factors, performing biopsies, and tailoring treatments based on the nature of the lesions, advocating for a comprehensive approach to mediastinal masses.
