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, pleural fibrosis, or some cancers (tumors within the bronchi, lung, or pleural cavity) and certain lymphomas associated with the mediastinal lymph nodes.
