[The small lung nodule: dealing with a frequent radiological finding]

Area of Science:

• Pulmonology
• Radiology
• Oncology

Context:

• Multidetector computed tomography (MDCT) frequently detects small pulmonary nodules (<10 mm) in high-risk individuals.
• The clinical significance of these small nodules varies, with a generally low risk of malignancy.

Purpose:

• To outline a risk-adjusted algorithm for managing small pulmonary nodules detected via MDCT.
• To guide the indication for invasive procedures based on malignancy risk, imaging findings, and nodule growth.

Summary:

• Small pulmonary nodules (<10 mm) are incidental findings in high-risk patients undergoing MDCT.
• Malignancy risk assessment considers individual patient factors, nodule appearance, and growth patterns.
• A tailored algorithmic approach aims to prevent missed lung cancers while minimizing unnecessary invasive procedures.

Impact:

• Facilitates evidence-based decision-making for the management of small pulmonary nodules.
• Reduces the rate of unnecessary invasive procedures in patients with benign nodules.
• Improves lung cancer detection rates by focusing invasive strategies on high-risk nodules.
