Chest X-ray showing the features of pneumothorax on the left side of the person (right in image) It is not unusual for the mediastinum (the structure between the lungs that contains the heart, great blood vessels, and large airways) to be shifted away from the affected lung due to the pressure differences.

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.
On chest x-ray, one lung will be significantly more inflated than the other, causing a mediastinal shift. Bullous emphysema's radiographic appearance on x-ray mimics a tension pneumothorax. This presents a medical challenge as these diseases are treated differently despite appearing similarly on x-ray. [24] [25]
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.
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 ...
In radiology, the deep sulcus sign on a supine chest radiograph is an indirect indicator of a pneumothorax. [1] [2] In a supine film, it appears as a deep, lucent, ipsilateral costophrenic angle [3] within the nondependent portions of the pleural space as opposed to the apex (of the lung) when the patient is upright.
Left-sided pneumothorax (right side of image) on CT scan of the chest with chest tube in place. Medical uses of chest tube are as follows: [6] Pneumothorax: accumulation of air or gas in the pleural space; Pleural effusion: accumulation of fluid in the pleural space Chylothorax: a collection of lymph in the pleural space
