Overview

  • A solitary pulmonary nodule is a round or oval spot (lesion) in the lungs that is seen with a chest x-ray or CT scan.

What are the symptoms of Solitary Pulmonary Nodule?

  • There are usually no symptoms.

What causes Solitary Pulmonary Nodule?

  • More than half of all solitary pulmonary are noncancerous (benign). Benign nodules have many causes, including old scars and infections.
  • Infectious granulomas are the cause of most benign lesions.
  • You have a greater risk for developing a solitary pulmonary nodule if you have:
  • Tuberculosis or been exposed to TB
  • Infectious lung diseases caused by fungus, such as:
  • Histoplasmosis
  • Coccidioidomycosis
  • Cryptococcosis
  • Aspergillosis
  • However, the above conditions makes it more likely that the solitary pulmonary nodule is noncancerous.
  • Young age, history of not smoking, calcium in the lesion, and small lesion size are factors associated with a noncancerous diagnosis.
  • Lung cancer is the most common cause of cancerous (malignant) pulmonary nodules.

When to seek urgent medical care?

  • A solitary pulmonary nodule is usually found by your health care professional when a chest x-ray is performed for some other reason.

Diagnosis

  • A solitary pulmonary nodule is usually found on a chest x-ray. If x-rays repeated over time show the nodule size has remain unchanged for 2 years, it is generally considered benign.
  • A chest CT scan is often done to look at a solitary pulmonary nodule in more detail.
  • Other tests used to examine a solitary pulmonary nodule may include:
  • PET scan
  • Percutaneous needle biopsy
  • Single-photon emission CT (SPECT) scan
  • Skin tests to rule out infectious causes
  • Lung biopsy

Treatment options

  • Ask your doctor about the risks of a biopsy versus monitoring the size of the nodule with regular x-rays.
  • Reasons for a biopsy or removing the nodule may include:
  • Smoking
  • The nodule size has grown compared to earlier x-rays
  • A CT scan suggests the lesion is malignant (cancerous)

What to expect (Outlook/Prognosis)?

  • The outlook is generally good if the nodule is benign.
  • If the nodule does not grow larger over a 2-year period, under most circumstances nothing more need be done. On occasion, the appearance of the nodule on CT scan may warrant continued follow-up.
