What causes enlarged mediastinal and hilar lymph nodes?

The most common causes of bilateral hilar adenopathy include sarcoidosis and lymphoma. Other less common causes include pulmonary edema and rheumatologic lung disorders such as rheumatoid arthritis. Many of the other listed disorders cause asymmetric enlargement of mediastinal lymph nodes.

Are mediastinal lymph nodes cancer?

They can be benign (not cancer) or malignant (cancer). Mediastinal tumors are growths that form in the area of the chest that separates the lungs. This area, called the mediastinum, is surrounded by the breastbone in front, the spine in back, and the lungs on each side.

What are hilar lymph nodes?

Station 11 lymph nodes, named left hilar lymph nodes, are between the left upper lobe and left lower lobe of the bronchus. The puncture sites for left hilar lymph nodes are at the lateral wall of the left lower lobe of the bronchus at about the 9 o’clock position, proximal to the left dorsal bronchus orifice.

Can hilar lymph nodes be removed?

The interlobar lymph nodes and hilar lymph nodes around the vessels should not be removed separately; rather, they should be dissociated to the distal end of the vessel and then removed en bloc with the right upper pulmonary lobe. This is more consistent with the principles of surgical oncology.

What causes a mediastinal mass?

The soft-tissue structures that compose the margins of the mediastinum and abut against the lungs usually cast discernible shadows on roentgenograms. These lung-mediastinal interfaces are keys to the radiologic
