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.
[3] [14] Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. [15] The severity of the condition is variable. [15] Pneumonia is usually caused by infection with viruses or bacteria, and less commonly by other microorganisms. [a] Identifying the responsible pathogen can be difficult.
