Pulmonary nodules are small, focal, radiographic opacities that may be solitary or multiple. A classic solitary pulmonary nodule (SPN) is a single, spherical, well-circumscribed, radiographic opacity measuring less than or equal to 30 mm in diameter and is surrounded completely by aerated lung.
There are many causes of pulmonary nodules. These include infection, such as fungal or bacterial infections, noncancerous processes, such as sarcoidosis, or cancerous processes, such as lung cancer, lymphoma, or metastatic cancer from other organs.ome patients might experience symptoms of a respiratory infection, such as a symptoms associated with chest colds or mild flu. Most pulmonary nodules are discovered by accident, when a patient gets a chest X-ray or a CT scan performed for another purpose.
