Radiological Features

Most cases are detectable by chest x-ray. Radiologic features are by far the most important in helping decide on the etiology of solitary pulmonary nodule. Systematic attention to the following features of the lesion enable the Radiologist to suggest a possible lesion.

• Location
• Size
• Margin
• Doubling time
• Calcification

Demonstartion of calcium and the stability of lesion over two year period are the most reliable findings to distinguish a benign from malignant lesion.
