A pulmonary hematoma is a collection of blood within the tissue of the lung. It may result when a pulmonary laceration fills with blood. [ 1 ] A lung laceration filled with air is called a pneumatocele . [ 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. The estimated number of Americans with pneumococcal pneumonia is 900,000 annually, with almost 400,000 cases hospitalized and fatalities accounting for 5-7% of these cases.

In yet another unexpected finding, 94 percent of patients in the study with the autoantibodies were men. About 12.5 percent of men with life-threatening Covid-19 pneumonia had autoantibodies ...
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 1 ] [ 2 ] [ 3 ] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
People may become infected with pneumonia in a hospital; this is defined as pneumonia not present at the time of admission (symptoms must start at least 48 hours after admission). [ 85 ] [ 84 ] It is likely to involve hospital-acquired infections , with higher risk of multidrug-resistant pathogens.
Usual interstitial pneumonia (UIP) is a form of lung disease characterized by progressive scarring of both lungs. [1] The scarring ( pulmonary fibrosis ) involves the pulmonary interstitium (the supporting framework of the lung).
Acute eosinophilic pneumonia can occur at any age, even in previously healthy children, though most patients are between 20 and 40 years of age. Men are affected approximately twice as frequently as women. Acute eosinophilic pneumonia has been associated with smoking. Chronic eosinophilic pneumonia occurs more frequently in women than men and ...
