It is the acute inflammation of the bronchi, accompanied by inflamed patches in the nearby lobules of the lungs. [1] It is often contrasted with lobar pneumonia; but, in clinical practice, the types are difficult to apply, as the patterns usually overlap. [2] Bronchopneumonia (lobular) often leads to lobar pneumonia as the infection progresses.
Bronchoscopy is an endoscopic technique of visualizing the inside of the airways for diagnostic and therapeutic purposes. An instrument (bronchoscope) is inserted into the airways, usually through the nose or mouth, or occasionally through a tracheostomy.
Cryptogenic organizing pneumonia; Other names: Bronchiolitis obliterans with organizing pneumonia, idiopathic interstitial pneumonia [1] Micrograph showing a Masson body (off center left/bottom of the image – pale circular and paucicellular), as may be seen in cryptogenic organizing pneumonia. The Masson body plugs the airway.
Lobar pneumonia is often due to Streptococcus pneumoniae (though Klebsiella pneumoniae is also possible.) [16] Multilobar pneumonia involves more than one lobe, and it often causes a more severe illness. Bronchial pneumonia affects the lungs in patches around the tubes (bronchi or bronchioles).
Common causes include congestive heart failure. [22] Stridor a high-pitched musical breath sound resulting from turbulent air flow in the larynx or lower in the bronchial tree. [23] It is not to be confused with stertor. Causes are typically obstructive, including foreign bodies, croup, epiglottitis, tumours, infection and anaphylaxis.
There are a variety of potential causes, including Pneumocystis pneumonia, late-stage adenocarcinoma, pulmonary edema, some types of idiopathic interstitial pneumonias, diffuse alveolar hemorrhage, sarcoidosis, and pulmonary alveolar proteinosis. [6] COVID-19 has also been shown to occasionally cause GGOs with a crazy paving pattern. [11]
It’s important to point out that Mycoplasma pneumoniae doesn’t always cause pneumonia. In fact, the CDC points out that it can also cause a simple cold. As a result, ...
An often used formal radiological definition is the following: a single lesion in the lung completely surrounded by functional lung tissue with a diameter less than 3 cm and without associated pneumonia, atelectasis (lung collapse) or lymphadenopathies (swollen lymph nodes). [13] [10]
