Overview

Lung mass can be classified into malignant and benign. In addition, lung mass can be sub-classified according to location, imaging features, and distribution.

Classification

Lung mass can be classified by location, histopathological origin, and imaging features into the following types:

• Pleural
• Endobronchial
• Parenchymal
 
 
 
• Malignant mass
• Benign mass
 
 
 
• Hyperdense pulmonary mass
• Cavitating pulmonary mass
