Contusion involves hemorrhage in the alveoli (tiny air-filled sacs responsible for absorbing oxygen), but a hematoma is a discrete clot of blood not interspersed with lung tissue. [4] A collapsed lung can result when the pleural cavity (the space outside the lung) accumulates blood or air (pneumothorax) or both (hemopneumothorax). These ...
In some lung diseases, especially emphysema, it is possible for abnormal lung areas such as bullae (large air-filled sacs) to have the same appearance as a pneumothorax on chest X-ray, and it may not be safe to apply any treatment before the distinction is made and before the exact location and size of the pneumothorax is determined. [15]
The lack of a clear cause means that diagnosis and treatment is difficult. The disease is believed to be largely undiagnosed or misdiagnosed, leaving the true frequency unknown in the general population. Catamenial pneumothorax is defined as at least two episodes of recurrent pneumothorax corresponding with menstruation.
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 ...
Causes include any obstruction of blood flow to and from the heart. There are multiple, including pulmonary embolism, cardiac tamponade, and tension pneumothorax. Other causes include abdominal compartment syndrome, Hiatal hernia, severe aortic valve stenosis, and disorders of the aorta. Constrictive pericarditis is a rare cause.
According to the Mayo Clinic, a pneumothorax can be caused by a blunt or penetrating chest injury, from underlying lung disease or for no obvious reason. McCollum’s right lung collapsed in 2021 ...
Before my thoracic endometriosis diagnosis, one doctor said, “I’ve only ever read about this in my textbooks. I didn’t think people actually got this.”
Therefore, pneumothorax is usually more of a problem than hemothorax. [8] A pneumothorax may form or be turned into a tension pneumothorax by mechanical ventilation, which may force air out of the tear in the lung. [12] The laceration may also close up by itself, which can cause it to trap blood and potentially form a cyst or hematoma. [8]
