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.
Mild to moderate scarring of the lungs has been found in unusual cases of pulmonary siderosis. These people have had persistent breathlessness , coughing and decreased lung function. However, people in occupations where they are exposed to iron (or rust) dust are usually also exposed to other forms of dust such as silica , which upon repeated ...
Causes include environmental pollution, certain medications, connective tissue diseases, infections, and interstitial lung diseases. [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]
The most common symptom of laryngotracheal stenosis is gradually-worsening breathlessness particularly when undertaking physical activities (exertional dyspnea).The patient may also experience added respiratory sounds which in the more severe cases can be identified as stridor but in many cases can be readily mistaken for wheeze.
Figure B shows fibrosis (scarring) in the lungs. The inset image shows a detailed view of the fibrosis and how it damages the airways and air sacs. [1] Specialty: Pulmonology: Symptoms: Shortness of breath, dry coughing [1] Complications: Pulmonary hypertension, heart failure, pneumonia, pulmonary embolism [1] Usual onset: Gradual [1] Causes ...
A pulmonary laceration can cause air to leak out of the lacerated lung [10] and into the pleural space, if the laceration goes through to it. [8] Pulmonary laceration invariably results in pneumothorax (due to torn airways), hemothorax (due to torn blood vessels), or a hemopneumothorax (with both blood and air in the chest cavity). [11]
Myocardial scarring is the accumulation of fibrous tissue resulting after some form of trauma to the cardiac tissue. [ 1 ] [ 2 ] Fibrosis is the formation of excess tissue in replacement of necrotic or extensively damaged tissue.
Sarcoid granulomas can resolve spontaneously without complications or heal with residual scarring. In the lungs, this scarring can cause a condition known as pulmonary fibrosis that impairs breathing. In the heart, it can lead to rhythm disturbances, heart failure, and even death.
