 +Collection of [[blood]] in the space between the chest wall and the [[lung]] (the [[pleural]] cavity.

 +The most common cause of hemothorax is chest [[trauma]]. Hemothorax can also occur in patients with lung or pleural cancer, or in patients with a defect of the blood clotting mechanism. The condition is also commonly linked with thoracic or heart [[surgery]],​ and can also occur in patients who suffer pulmonary infarction (death of lung [[tissue]]).
 +
 +In blunt chest trauma, a rib may lacerate lung tissue or an [[artery]], causing blood to collect in the pleural space. In penetrating chest trauma, a weapon such as a knife or bullet lacerates the lung.
 +
 +A large hemothorax is often a cause of shock in a trauma victim. Hemothorax may also be associated with [[pneumothorax]] (air trapped in the pleural cavity). Depending on the amount of blood or air in the pleural cavity, a collapsed lung can lead to respiratory and hemodynamic failure (tension pneumothorax).

 +Hemothorax can also be a complication of [[tuberculosis]].
