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.
Necrotizing pneumonia [5] Vasculitis: Granulomatosis with polyangiitis; Necrotizing tumors: 8% to 18% are due to neoplasms across all age groups, higher in older people; primary squamous carcinoma of the lung is the most common.

Seniors are generally at higher risk for complications and death from pneumonia due to weakened immune systems. However, risk factors vary from person to person. If you suspect your elderly loved ...
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.
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 ]
Changes in temperature or humidity are common causes of nonallergic rhinitis, the Mayo Clinic says. For some, weather changes can "create extra inflammation for people," Rubin said, which can ...
Pneumonia fills the lung's alveoli with fluid, hindering oxygenation. The alveolus on the left is normal, whereas the one on the right is full of fluid from pneumonia. Pneumonia frequently starts as an upper respiratory tract infection that moves into the lower respiratory tract. [55] It is a type of pneumonitis (lung inflammation). [56]
