There are usually no symptoms.

A solitary pulmonary nodule is usually found on a chest x-ray. If serial chest x-rays (repeated x-rays over time) show the nodule size unchanged for 2 years, it is considered benign. A chest CT scan is often performed to evaluate a solitary pulmonary nodule in detail.

Other tests may include the following:

• PET scan
• Single-photon emission CT (SPECT)
• Skin tests to rule out infectious causes
• Percutaneous needle biopsy
• Surgical lung biopsy
