Overview
On conventional radiography, characteristic findings of solitary pulmonary nodule include well-defined, small, and rounded opacities within the pulmonary interstitium, usually 8 mm in diameter and normally surrounded by normal aerated lung.
X Ray
- Conventional chest x-ray may be helpful in the diagnosis of pulmonary nodule.
- The majority of pulmonary nodules require further evaluation with CT scan and MRI.
- On conventional radiography, characteristic findings of pulmonary nodule include:[1]
- Soft-tissue density mass
- Round or oval in shape
- Smooth margin
- Diameter of 8 mm and irregular margins
- Surrounded by areas of ground glass change

Malignant pulmonary nodule: The patient is a 67 year old woman with a solitary pulmonary nodule on a recent chest x-ray. A retrospective review of prior chest x-rays suggests that this nodule is of recent origin.

Arteriovenous malformations: Pulmonary arteriovenous malformation consistent with the finding of pulmonary nodule is seen in this image. There is breathing artifact on several of the images and other tiny AVMs cannot be excluded.
