Solitary Pulmonary Nodules

  • David Esposito

Solitary pulmonary nodules (SPNs) are defined as solitary lesions surrounded by normal lung parenchyma, not associated with atelectesis or hilar enlargement. In the past, lesions as large as 6 cm were classified as SPN, but now an appreciation that lesions ≥3 cm are almost always malignant has led to the belief that a 3 cm cutoff may be more useful. Lesions >3cm are sometimes referred to as solitary mass lesions. They are most often found on routine chest x-ray (CXR; incidence 0.1–2%: 130,000 new SPN/year) and are usually asymptomatic.
