A pulmonary contusion, also known as lung contusion, is a bruise of the lung, caused by chest trauma. As a result of damage to capillaries , blood and other fluids accumulate in the lung tissue. The excess fluid interferes with gas exchange , potentially leading to inadequate oxygen levels ( hypoxia ).
A pulmonary hematoma is a collection of blood within the tissue of the lung. It may result when a pulmonary laceration fills with blood. [1] A lung laceration filled with air is called a pneumatocele. [1] In some cases, both pneumatoceles and hematomas exist in the same injured lung. [2]
A chest tube must be inserted to drain blood and air from the pleural space so it can return to a state of negative pressure and function normally. [citation needed] Commonly, surgery is needed to close off whatever injuries caused the blood and air to enter the cavity (e.g. stabbing, broken ribs).
Flail chest is usually accompanied by a pulmonary contusion, a bruise of the lung tissue that can interfere with blood oxygenation. [5] Often, it is the contusion, not the flail segment, that is the main cause of respiratory problems in people with both injuries. [6] Surgery to fix the fractures appears to result in better outcomes. [7]

A hemothorax (derived from hemo-[blood] + thorax [chest], plural hemothoraces) is an accumulation of blood within the pleural cavity.The symptoms of a hemothorax may include chest pain and difficulty breathing, while the clinical signs may include reduced breath sounds on the affected side and a rapid heart rate.
Patients are seen with a cyanotic discoloration of the shoulder skin and neck and face, jugular distention, bulging of the eyeballs, and swelling of the tongue and lips. The latter two are resultants of edema, caused by excessive blood accumulating in the veins of the head and neck and venous stasis.
Benign conditions potentially leading to the formation of nodular GGOs include aspergillosis, acute eosinophilic pneumonia, focal interstitial fibrosis, granulomatosis with polyangiitis, IgA vasculitis, organizing pneumonia, pulmonary contusion, pulmonary cryptococcus, and thoracic endometriosis. Focal interstitial fibrosis presents a unique ...
