Necrotizing Pneumonia or necrotizing cavitary pneumonia is a rare bacterial lung infection. It is a severe condition caused by tissue death due to a lack of oxygen. Furthermore, in necrotizing pneumonia, the lungs receive reduced vascular supply leading to cellular death. The lack of blood supply impairs antibiotics’ delivery and subsequent effect.

This further boosts the advancement of infectious disease. It is a severe complication of parenchymal infection.

Hence, the build-up of cavities and liquids in the lung tissue leads to necrotizing cavitary pneumonia.

Furthermore, the infected compressed lung blocks alveolar capillaries reducing the vascular supply to the lung parenchyma. This disease may cause serious complications such as septic shock, respiratory failure, diffuse pulmonary inflammation, and making treatment more difficult.

How long does it take for Necrotizing Pneumonia to develop?

The quick onset of symptoms, even two or three hours after inhaling an infectious substance. However, it might take a day or more for necrotizing pneumonia to develop.

Necrotizing Cavitary Pneumonia: Causes

Necrotizing cavitary pneumonia occurs due to impaired defenses and inhaling excessively harmful materials. These materials include:

  • Food or beverages.
  • Small foreign objects.
  • Stomach contents such as digestive juices.
  • Bacteria from saliva and secretions.

More importantly, you can also develop it if your food goes down the wrong pipe and your coughing ability is impaired. Similarly, multiple risk factors are associated with inhaling foreign materials into the lungs. Again, you must be careful about these and avoid getting seriously ill. Some of them include:

  • Poor gag reflex.
  • Drinking excessive alcohol.
  • Weakened immune system.
  • Esophageal disorders.
  • Neurological disorders.
  • Medical conditions like Parkinsons’ disease.
  • Stroke.
  • Throat cancer.
  • Seizures.

Furthermore, this infectious disease can also occur due to a poisonous factor of the microorganism. Moreover, recently the cause of this infectious disease and the role of surgical treatment has raised significant attention.

What are the symptoms of Necrotizing Pneumonia?

Patients suffering from necrotizing pneumonia usually complain about the following problems:

  • Fever.
  • Chest pain.
  • Shortness of breath.
  • Coughing blood or pus.
  • Extreme tiredness.
  • Dangerously low blood pressure.
  • Abnormal reduction in white blood cells.
  • Severe respiratory symptoms.
  • Bad breath.
  • Wheezing.
  • Excessive sweating.
  • Discoloration of skin.
  • Pulmonary inflammation.

Furthermore, in many cases, the issue gets resolved. However, a high mortality rate is associated with this infectious disease.


Firstly, your doctor will perform a physical examination and take a complete medical history. They will ask about the symptoms, the onset, and the frequency in which they occur. Additionally, some doctors can also look for signs of necrotizing pneumonia, such as rapid heart rate. Furthermore, they also check for decreased flow of air, and a crackling sound in your lungs. In addition to that, they may run a series of tests that include:

  • Chest X-ray.
  • Sputum tests.
  • Blood tests.
  • Bronchoscopy.
  • Complete blood count (CBC).
  • Computed tomography (CT) scan of the chest area.
  • Blood culture.
  • Arterial blood gas.
  • Swallowing tests.

Moreover, due to the severity of this infectious disease, it requires good treatment. After getting your test results in 1 to 5 days, you must proceed toward treatment.

How is Necrotizing Pneumonia treated?

The treatment of necrotizing pneumonia depends on the severity of your pneumonia. Your doctor might prescribe antibiotics and antiviral therapy. The choice of medication will depend on several situations. Individuals should get treated for infections with antibiotics that are effective against many types of bacteria. These might include allergic reactions to specific drugs and where you got infected. It is vital to take these antibiotics for the entire prescription period. Additionally, this disease can cause breathing issues. You will need additional treatment that will include oxygen therapy. Furthermore, in life-threatening situations, mechanical ventilation is essential to support breathing.

In some cases, hospitalization becomes necessary. If people face trouble swallowing, their doctor might advise them to use other feeding methods. Moreover, depending on the severity of your disease, you might require surgery. Furthermore, the outcome of treatment depends on your overall health. In severe cases. Doctors often suggest hospitalizing the patient. However, preventing necrotizing pneumonia is essential to decrease the chances of further infection or inflammation.


You can do a couple of things to avoid getting infected by this type of pneumonia. Preventive measures include:

  • Stay upright while eating or drinking.
  • Chew slowly.

Most people who suffer from this infectious disease get treatment and survive. Furthermore, the prognosis of the disease also depends on the patient’s overall health. Additionally, the type of bacteria that caused pneumonia can determine how severe the condition is. Moreover, untreated necrotizing pneumonia can be very dangerous. It might result in long-term damage to the lungs. This will affect your swallowing and can cause permanent scarring of the lungs.

Although you might get a good sign from your doctor, you can still feel tired after some time. In many cases, people feel tired up to months from recovery. Plus, it can also occur due to medical conditions like neurological disorders that can be hard to treat.


Some of the complications of necrotizing cavitary pneumonia may include:

  • Shock.
  • Respiratory failure.
  • Spread of infection to the bloodstream.
  • Spreading of the infection to specific areas of the body.
  • Lung infections.
  • Death.

Who is at risk from necrotizing pneumonia?

Young adults and children face the highest risk from necrotizing cavitary pneumonia. Children are more at risk of lung diseases because their lungs are still in the developmental stage. They play with dirt and explore new things. That can lead to infections related to the lungs. Furthermore, when the weather changes, children get infected with this disease, which can also lead to death in adults and children.

Moreover, the clinical features of necrotizing pneumonia are similar to those of community-acquired pneumonia. That makes it harder to distinguish between them. Often children come down with respiratory symptoms and get treatment for community-acquired pneumonia. But their condition worsened. That is because they were suffering from necrotizing pneumonia.

Necrotizing Cavitary Pneumonia: Contact your doctor now

If you start to have symptoms like fever or chest pain, consult your doctor immediately. Furthermore, if you have difficulty breathing and are often choking, seek emergency medical help. Moreover, it is vital to treat pneumonia before it gets worse.

Necrotizing Pneumonia: Takeaway

Necrotizing pneumonia can infect and inflame the lungs. It makes breathing difficult for the individual. But you have the right to plan your care. So, keep learning about your health and how to get proper treatment for specific medical conditions. You can select the right treatment option that will benefit you by consulting your doctor.
