Pulmonary mass is generally defined as any area of pulmonary opacification that measures more than 30 mm in the lung. Pulmonary mass can be benign or malignant. On the other hand, pulmonary nodule is defined as a relatively well defined round or oval pulmonary parenchymal lesion equal or smaller than 30 mm in diameter. Pulmonary nodule can be classified into 2 categories: solitary or multiple.

Overview

Pulmonary mass (also known as lung mass) is generally defined as any area of pulmonary opacification that measures more than 30 mm in the lung. Pulmonary mass can be benign or malignant. On the other hand, pulmonary nodule is defined as a relatively well defined round or oval pulmonary parenchymal lesion equal or smaller than 30 mm in diameter. Pulmonary nodule can be classified into 2 categories: solitary or multiple.
