Description

A partial lung collapse is called "atelectasis". Most often it is only one of the segments of the lower lung lobes that is adjacent to the diaphragm. The reason for this is that a mucous plug can form easier in the lower bonchial tubes. This is particularly the case in older patients. They are too weak to cough it up, or in otherwise sick patients. Atelectasis is often associated with chronic lung diseases such as COPD, asthma, ARDS, bronchiectasis or lung cancer. One special subcategory is a "rounded atelectasis", due to the appearance of a round lesion on X-rays, which is usually located close to the diaphragm and is associated with asbestosis.
