II. Pathophysiology
-
Lung consolidates as gas is absorbed from obstructed segments
- Lung parenchyma decreases in volume and becomes more dense
- Consolidated lung gradually becomes more visible on plain Chest XRay
- Consolidated lung density matches the density of soft tissue
- Obscures normal lung landmark structures (e.g. mediastinum, costophrenic angle)
III. Findings
- Mediastinal shift
- Massive whole lung collapse
- Lower lobe collapse
- Tracheal Deviation
- Occurs with whole lung collapse
- Trachea deviates toward the area of lung collapse
- Upward hilar displacement
- Upper lobe collapse
- Downward hilar displacement
- Lower lobe collapse
- Shift of fissures
- Affects any segment
- May shift from horizontal to vertical orientation
- Narrowing of costal interspaces
- Massive Atelectasis

Definition (MSH) | Absence of air in the entire or part of a lung, such as an incompletely inflated neonate lung or a collapsed adult lung. Pulmonary atelectasis can be caused by airway obstruction, lung compression, fibrotic contraction, or other factors. |
Definition (MSHCZE) | Nepřítomnost vzduchu v celých plicích nebo jejich části např. u nedovyvinutých plic novorozence nebo při plicním kolapsu dospělých. Plicní atelektáza může být způsobená vzduchovou obstrukcí, plicní kompresí, fibrózním zmnožením tkáně (kolapsová plicní indurace) nebo z jiné příčiny. |
Definition (MEDLINEPLUS) |
A collapsed lung happens when air enters the pleural space, the area between the lung and the chest wall. If it is a total collapse, it is called pneumothorax. If only part of the lung is affected, it is called atelectasis. Causes of a collapsed lung include
If only a small area of the lung is affected, you may not have symptoms. If a large area is affected, you may feel short of breath and have a rapid heart rate. A chest x-ray can tell if you have it. Treatment depends on the underlying cause. NIH: National Heart, Lung, and Blood Institute |
Definition (NCI_CTCAE) | A disorder characterized by the collapse of part or the entire lung. |
Definition (NCI) | The collapse of part or the entire lung due to airway obstruction, infection, tumor, or general anesthesia. |
Definition (NCI_NCI-GLOSS) | Failure of the lung to expand (inflate) completely. This may be caused by a blocked airway, a tumor, general anesthesia, pneumonia or other lung infections, lung disease, or long-term bedrest with shallow breathing. Sometimes called a collapsed lung. |
Definition (CSP) | collapse of all or part of a lung due to bronchial plugging or the chest cavity being opened to atomspheric pressure. |
