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]
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.

[29] Atypical presentation is common in the elderly. Older patients may have impaired T cell function and hence, they may be unable to mount a febrile response.
