Traumatic pneumothoraces may be classified as "open" or "closed". In an open pneumothorax, there is a passage from the external environment into the pleural space through the chest wall. When air is drawn into the pleural space through this passageway, it is known as a "sucking chest wound". A closed pneumothorax is when the chest wall remains ...
Chest x-ray demonstrating severe atelectasis or collapse of the right lung and mediastinal shift towards the right. Atelectasis is the partial collapse of a lung that is reversible. There are numerous etiologies, including post-operative atelectasis, surfactant deficiency, mucus plugging, and foreign body aspiration.

During inspiration, only subtle pneumothorax is seen in the apical part of the left thoracic cavity. It can practically be diagnosed only by the absence of vascularity in the most apical lung segment. It is seen more clearly posteriorly on lateral X-ray. During expiration, the pneumothorax takes up approximately 50% of the cavity.
Image shows early occurrence of tracheal deviation. Tracheal deviation is a clinical sign that results from unequal intrathoracic pressure within the chest cavity.It is most commonly associated with traumatic pneumothorax, but can be caused by a number of both acute and chronic health issues, such as pneumonectomy, atelectasis, pleural effusion, fibrothorax (pleural fibrosis), or some cancers ...
A chest radiograph, chest X-ray (CXR), or chest film is a projection radiograph of the chest used to diagnose conditions affecting the chest, its contents, and nearby structures. Chest radiographs are the most common film taken in medicine.
Chest X-ray is known to be unreliable in diagnosing diaphragmatic rupture; [4] it has low sensitivity and specificity for the injury. [5] Often another injury such as pulmonary contusion masks the injury on the X-ray film. [6] Half the time, initial X-rays are normal; in most of those that are not, hemothorax or pneumothorax is present. [4]
Air is trapped in the chest cavity outside the lungs (pneumothorax) in about 70% of TBI. [4] [10] Especially strong evidence that TBI has occurred is failure of a pneumothorax to resolve even when a chest tube is placed to rid the chest cavity of the air; it shows that air is continually leaking into the chest cavity from the site of the tear.
