Chest X-Ray - Lung disease. Publicationdate February 1, 2014. On a chest x-ray lung abnormalities will either present as areas of increased density or as areas of decreased density. Lung abnormalities with an increased density - also called opacities - are the most common.

The amount of lung tissue involved in atelectasis is variable, depending on the cause. Atelectasis can make breathing difficult and lower oxygen particularly if lung disease is already present. Treatment depends on the cause and severity of the collapse.

There is a right lower lobe atelectasis. Notice the abnormal right border of the heart. The right interlobar artery is not visible, because it is not surrounded by aerated lung but by the collapsed lower lobe, which is adjacent to the right atrium. On a follow-up chest film the atelectasis has resolved.

Whenever you see an area of increased density within the lung, it must be the result of one of these four patterns. Consolidation - any pathologic process that fills the alveoli with fluid, pus, blood, cells (including tumor cells) or other substances resulting in lobar, diffuse or multifocal ill-defined opacities.

By Mayo Clinic Staff. Atelectasis (at-uh-LEK-tuh-sis) — a complete or partial collapse of a lung or lobe of a lung — develops when the tiny air sacs (alveoli) within the lung become deflated. It's a breathing (respiratory) complication after surgery. Atelectasis is also a possible complication of other respiratory problems, including cystic fibrosis, inhaled foreign objects, lung tumors, fluid in the lung, respiratory weakness and chest injuries.

TP usually occurs after trauma to the chest or lung wall has occurred. The trauma can damage these structures, and this allows air to leak into the pleural space. Examples of traumas that can cause TP include: air bag impact in a vehicle accident.

More specifically, a pneumothorax begins as a hole in the lung, which allows air to escape from inside the lung and inflates the space between the lung and the ribcage. Pressure from this enlarging pocket of air causes the lung to collapse.

On a chest X-ray UIP manifests as a reticular pattern particularly at the lung bases. In many cases you can suspect UIP on the CXR. A HRCT is needed to confirm the diagnosis by demonstrating honeycombing. Here a CXR with a reticular pattern at the lung bases.

Pneumothorax occurs when air enters the space around your lungs, or the pleural space. Air can find its way into the pleural space when there’s an open injury in your chest wall or a tear or rupture in your lung, disrupting the pressure that keeps your lungs inflated. It’s known as a tension pneumothorax when the lung wall is affected, or an open pneumothorax when the chest wall is affected. Causes of ruptured or injured chest or lung walls can include lung disease, injury from a sport, or even changes in air pressure that you experience when scuba diving or mountain climbing. Sometimes, the cause of pneumothorax is unknown.

The characteristic symptom of a collapsed lung from pneumothorax is severe, sharp chest pain and difficulty breathing. Atelectasis symptoms include possible chest pain or pressure, cough, and difficulty breathing. Treatment for a collapsed lung includes procedures to re-inflate the affected lung, ease breathing, and increase oxygenation. In rare cases, surgery is required to repair the damaged lung. Remembering to take deep breaths every hour, if you are bedridden or have pain with breathing, can prevent atelectasis.
