Necrotic pneumonia is typically due to a bacterial infection that begins to destroy the lung tissue. The most common type of bacteria that causes necrotic pneumonia is Streptococcus pneumoniae, though other species are increasingly being identified in sputum cultures of individuals with this serious form of pneumonia.iagnosis. You can typically diagnose necrotic pneumonia from an X-ray of the chest. A chest X-ray will show pockets or cavities of destroyed tissue, as well as a buildup of fluid in these areas of dead lung tissue. The lungs may also be surrounded by pus or pleural fluid due to the inflammation and tissue damage.
âPneumonia is a serious lung infection causing an inflammation of the lung tissue,â said Patrick M. Jarvis, M.D., internal medicine physician, Norton Inpatient Specialists. âYour lungs become infected with a pathogen, either bacterial or viral, when you breathe in or come in contact with these organisms.â. Dr. Jarvis said that in some cases pneumonia develops as a result of other illnesses, such as the flu, bronchitis or other upper respiratory infections that linger. âIf you are a normally healthy person, a small amount of the organism getting into your lungs may not cause an infection.
