The left main bronchus was exposed at the posterior mediastinum and separated from connective tissue.
On the lateral radiograph there appeared to be herniation of the left lung through the anterior mediastinum .
The tumor, which is often but not always associated with cystic lung lesions, may arise in pulmonary parenchyma, the mediastinum , and pleura.
A peritoneal sac protrudes through the hiatus into the mediastinum next to the esophagus.
The most common sites of tumor metastases are the lymph nodes in the mediastinum .
A single enlarged anterior mediastinal lymph node was also identified.
One patient had extensive cervical, posterior mediastinal , and abdominal lymphadenopathy.
In addition, she had a mediastinal lymph node dissection.
Two patients presented with masses in the upper lobe of the right lung, simulating posterior mediastinal tumors.
All men with mediastinal lung masses require a careful testicular examination.
