Imaging can be diagnosed.

Except for the medical history, the diagnosis is mainly based on clinical manifestations. However, because mediastinitis is part of the entire process of infection, and simple mediastinitis is on the X-ray, there is no special manifestation except for the possibility of widening of the mediastinal shadow and mediastinal emphysema. More seen above are localized mediastinal abscesses, or posterior mediastinal manifestations of gas-liquid surface, pneumothorax, etc. on lateral chest radiographs, and sometimes the diagnosis is not easy. Anterior and lateral chest radiographs are important for X-ray examinations. Observation of general bedside photography is not clear due to the conditions of projection. For the convenience of diagnosis, it is best to take an anterior chest radiograph and a lateral chest radiograph after the semi-sitting position. If esophageal or tracheal rupture is suspected, 40% sterile iodine oil imaging can be performed, and barium is avoided to avoid long-term retention and stimulate the tissue.
