Lobar pneumonia is a form of pneumonia characterized by inflammatory exudate within the intra-alveolar space resulting in consolidation that affects a large and continuous area of the lobe of a lung. [1] [2] It is one of three anatomic classifications of pneumonia (the other being bronchopneumonia and atypical pneumonia).
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 5 ] [ 6 ] [ 7 ] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
Findings on chest x-ray supportive of aspiration pneumonia include localized consolidation depending on the patient's position when the aspiration occurred. [18] For example, people that are supine when they aspirate often develop consolidation in the right lower lobe of the lung. [18]
In adults, the right lower lobe of the lung is the most common site of recurrent pneumonia in foreign body aspiration. [2] This is due to the fact that the anatomy of the right main bronchus is wider and steeper than that of the left main bronchus, allowing objects to enter more easily than the left side. [2]
Pneumonia as seen on chest X-ray. A: Normal chest X-ray. B: Abnormal chest X-ray with consolidation from pneumonia in the right lung, middle or inferior lobe (white area, left side of image). Specialty: Pulmonology
Since pneumonia can take a dangerous turn, it's important to know the earliest signs of it. Dr. Zweig says that, typically, pneumonia starts as a regular viral upper respiratory infection.
Occult pneumonia, however, can also be the result of atypical pneumonia. [2] Chest x-ray, showing pneumonia in right lower lobe. Although pneumococcal vaccination lowers the prevalence of occult pneumonia, it does not make radiographic diagnosis superfluous at patients with prolonged fever, cough or leukocytosis. [1] [3]
What happens if walking pneumonia is left untreated? 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 ...
