Atelectasis is the partial collapse or closure of a lung resulting in reduced or absence in gas exchange. It is usually unilateral, affecting part or all of one lung. [2] It is a condition where the alveoli are deflated down to little or no volume, as distinct from pulmonary consolidation, in which they are filled with liquid.
In both CT and chest radiographs, normal lungs appear dark due to the relative lower density of air compared to the surrounding tissues. When air is replaced by another substance (e.g. fluid or fibrosis), the density of the area increases, causing the tissue to appear lighter or more grey.
[1] [3] [6] But in most cases the cause is unknown (idiopathic pulmonary fibrosis). [1] [3] Diagnosis may be based on symptoms, medical imaging, lung biopsy, and lung function tests. [1] No cure exists and treatment options are limited. [1] Treatment is directed toward improving symptoms and may include oxygen therapy and pulmonary rehabilitation.
A linear scar may also form after treatment, but this can usually be minimized with massage and steroids. Healing time is short, and effectiveness is very high. [11] A newer procedure uses a carbon dioxide laser to ablate the vermillion border. This treatment is relatively quick and easy to perform, but it requires a skilled operator.
Pulmonary laceration is a common result of penetrating trauma but may also be caused by blunt trauma; broken ribs may perforate the lung, or the tissue may be torn due to shearing forces [5] that result from different rates of acceleration or deceleration of different tissues of the lung. [6]
