Overview

According to the Fleischner Society, solitary pulmonary nodules may be classified by size, distribution, and attenuation, into 5 categories: solid nodules measuring >8 mm in diameter, solid nodules measuring ≤8 mm in diameter, pure subsolid nodules, part-solid nodules, and multiple nodules.

Classification

Pulmonary nodules may be classified by size, attenuation, and distribution into the following:

Size

• Solid nodules measuring >8 mm and < 30 mm in diameter
• Solid nodules measuring ≤8 mm in diameter

Attenuation

• Pure subsolid nodules
• Part-solid nodules

Distribution

• Solitary pulmonary nodule
• Multiple pulmonary nodules
