Sarcoidosis is a rare inflammatory disease that causes small lumps, called granulomas, to collect and affect tissue function. When this condition is present in the lungs, it is called pulmonary sarcoidosis. With pulmonary sarcoidosis, the granulomas affect how the lungs work and can cause further damage—and hinder the transfer of oxygen to the bloodstream—if they do not heal and go away on their own.  

Pulmonary Sarcoidosis Causes 

Medical experts still do not know the exact cause of pulmonary sarcoidosis, though they believe that the condition may be brought on by a few potential factors, including: 

  • Bacterial infections 
  • Viral infections
  • Genetics 

Recognizing the Symptoms of Pulmonary Sarcoidosis 

Most people with pulmonary sarcoidosis do not show clear symptoms, making it difficult for them to know that they have the disease. If symptoms do appear, they may show up as: 

  • Shortness of breath 
  • Chest pain 
  • A dry, persistent cough 
  • Wheezing 
  • Fatigue 
  • Fever or night sweats 
  • Unexplained weight loss 
  • Swollen lymph nodes 
  • Inflammation and pain of the eyes 

Many of these symptoms affect organs other than the lungs, so identifying the signs of pulmonary sarcoidosis is more difficult.  

Diagnosing Pulmonary Sarcoidosis 

Like most lung conditions, diagnosing pulmonary sarcoidosis will require a medical professional to inquire about your medical history, conduct a physical exam and also perform additional testing.  

Your doctor may recommend: 

  • Imaging scans such as a chest X-ray or CT scan 
  • Pulmonary function tests to measure the lungs’ air-moving ability 
  • Blood tests to check blood oxygen levels and rule out other diseases 
  • A bronchoscopy to allow the doctor to view the airways of the lungs 
  • A lung biopsy to remove a small piece of lung tissue to be viewed under a microscope 

Oftentimes, a pulmonary sarcoidosis diagnosis will occur when other lung conditions have been ruled out.  

How is Pulmonary Sarcoidosis Treated? 

In many cases, pulmonary sarcoidosis will heal and go away on its own without additional treatment. If symptoms are present or if the condition is severe, a medical professional may recommend rehabilitation programs, steroid medication to reduce inflammation or methotrexate if steroids do not work. In rare cases, oxygen therapy and even a lung transplant may be needed.  

The pulmonary specialists at Tampa General Hospital expertly treat severe cases of pulmonary sarcoidosis and develop a personalized treatment plan for each patient. TGH is also a highly ranked transplant hospital, and our healthcare professionals can evaluate a patient’s need for a lung transplant on a case-by-case basis.
