The root of the lung is a group of structures that emerge at the hilum of each lung, just above the middle of the mediastinal surface and behind the cardiac impression of the lung. It is nearer to the back (posterior border) than the front (anterior border). The root of the lung is connected by the structures that form it to the heart and the ...
The pulmonary pleura covers the entire lung parenchyma. It meets the mediastinal pleura at the root of the lung ("hilum") through a smooth fold known as pleural reflection. A bell sleeve-like extension of the pulmonary pleura hanging under to the hilum is known as the pulmonary ligament.
Video-assisted thoracoscopic lung biopsy is the most definitive technique, but transbronchial biopsy has a yield of over 50% and can also be effective. [ 82 ] [ 83 ] The safety of the latter procedure in patients with diffuse cystic disease and the profusion of cystic change that predicts an informative biopsy are incompletely understood, however.

The most common symptom is sudden pain in one side of the lung and shortness of breath. A pneumothorax also can put pressure on the lung and cause it to ...

Anatomic lung resection, i.e. pulmonary lobectomy or pneumonectomy, in conjunction with removal of the lymph nodes from the mediastinum is the treatment modality that provides the greatest chance of long-term survival in patients with early stage non-small cell lung cancer.
