Abscess - A pocket of fluid and bacteria may appear on X-ray as a cavity in the lung. Abscesses, typical of aspiration pneumonia , usually contain a mixture of anaerobic bacteria . Although antibiotics can usually cure abscesses, sometimes they require drainage by a surgeon or radiologist .
Pneumonia as seen on chest x-ray. A: Normal chest x-ray.B: Abnormal chest x-ray with shadowing from pneumonia in the right lung (left side of image).. Hospital-acquired pneumonia (HAP) or nosocomial pneumonia refers to any pneumonia contracted by a patient in a hospital at least 48–72 hours after being admitted.
With treatment, most types of bacterial pneumonia will stabilize in 3–6 days. [2] It often takes a few weeks before most symptoms resolve. [2] X-ray findings typically clear within four weeks and mortality is low (less than 1%). [24] [140] In the elderly or people with other lung problems, recovery may take more than 12 weeks.
Pneumonia can lead to the development of a lung abscess, [4] which is a pus-containing necrotic lesion of the lung parenchyma (lung tissue). [5] On CT scan of the chest, a lung abscess appears as an intermediate- or thick-walled cavity with or without an air-fluid level (a flat line separating the air in the cavity from the fluid). [4]
The chest x-ray is distinctive with features that appear similar to an extensive pneumonia, with both lungs showing widespread white patches. The white patches may seem to migrate from one area of the lung to another as the disease persists or progresses. Computed tomography (CT) may be used to confirm the diagnosis.
To differentiate pyogenic liver abscess from amoebic liver abscess, several features such as subjects with age more than 50 years with lungs involvement, multiple liver abscesses, with amoebic serologic titres less than 1:256 can help to pin down the diagnosis of pyogenic liver abscess.

Chest radiographs (X-ray photographs) often show a pulmonary infection before physical signs of atypical pneumonia are observable at all. [5] This is occult pneumonia . In general, occult pneumonia is rather often present in patients with pneumonia and can also be caused by Streptococcus pneumoniae , as the decrease of occult pneumonia after ...
Pneumococcal pneumonia is a type of bacterial pneumonia that is caused by Streptococcus pneumoniae (pneumococcus). [1] It is the most common bacterial pneumonia found in adults, the most common type of community-acquired pneumonia, and one of the common types of pneumococcal infection.
