Patient, male, 42 years old. Chest tightness discomfort for 6 years, increase 1 year. There were no abnormalities in physical examination, electrocardiogram, and echocardiography. The chest X-ray film shows the anterior inferior mediastinum and extends to the left and right chest (visible in the left chest cavity). The CT scan showed a blocky shadow of the anterior inferior mediastinum and the left and right thoracic cavity and the pericardium (convexity was evident in the left thorax). The diagnosis was anterior inferior mediastinal tumor. In February 1995, under general anesthesia, a 45-degree right chest was lying. The left anterolateral incision was inserted into the chest through the 5th intercostal space, and then the incision was transected and the sternum was transected. The precordial area and left diaphragm muscles were seen on the left and the left. The pale yellow mass projecting into the right chest cavity occupies the left thoracic cavity and adheres to the diaphragm, pericardium, sternum, and left lung tissue, and is carefully separated.
