The Posterior Mediastinum

In this presentation, Dr. Chalian, a radiologist at the University of Utah, discusses the posterior mediastinum-a potential space with defined boundaries that communicates with the retrosternal space and intraabdominal cavity. Dr. Charan explores various structures within the posterior mediastinum, including the descending thoracic aorta, nervous structures, the azygos venous system, and the thoracic duct. The presentation includes cases for audience consideration, covering topics such as aortic aneurysm, mediastinal lymphoma, extramedullary hematopoiesis, splenosis, nerve sheath tumors, thymic conditions, lymphatic structures, and hiatal hernias. Each case is accompanied by imaging findings and differential diagnoses, providing valuable insights for medical practitioners dealing with posterior mediastinal pathologies.
