Anterior mediastinum

Dr Craig Hacking and Dr Jeremy Jones et al.

The anterior mediastinum is the portion of the mediastinum anterior to the pericardium and below the thoracic plane.

It forms the anterior part of the inferior mediastinum, and contains the thymus, lymph nodes, and may contain the portions of a retrosternal thyroid.
