Solitary  Pulmonary Nodule

More than half of all solitary pulmonary nodules are noncancerous (benign). 

Benign nodules have many causes, including old scars and infections.

Infectious granulomas (reactions to a past infection) cause most benign lesions.

Common infections that increase the risk of developing a solitary pulmonary nodule include:

  • Tuberculosis or having been exposed to TB
  • Lung diseases caused by a fungus, such as: Aspergillosis, Coccidioidomycosis, Cryptococcosis, Histoplasmosis

Lung cancer is the most common cause of cancerous (malignant) pulmonary nodules.

  • Solid nodule 

  • Ground Glass nodule
