A lung nodule or pulmonary nodule is a relatively small focal density in the lung. This article deals with the presence a solitary pulmonary nodule (SPN) or coin lesion, which is a mass in the lung smaller than 3 centimeters in diameter.
The content may be applied to the presence of a few solitary pulmonary nodules, each of which is defined as a single lesion in the lung completely surrounded by functional lung tissue with a diameter less than 3 cm, and without associated pneumonia, atelectasis (lung collapse) or lymphadenopathies.
Choice of investigation
- CT of lung nodules is the modality of choice for reevaluating solitary pulmonary nodules visible on X-ray of the thorax, and for subsequent monitoring.
