==Overview==
Lung masses may be classified into 2 types: malignant or benign lung masses. In addition, lung masses can be sub-classified according to location, imaging features, and distribution.
Lung mass can be [[Classification|classified]] into [[malignant]] and [[benign]]. In addition, lung mass can be sub-[[Classification|classified]] according to location, [[imaging]] features, and distribution.


==Classification==
==Classification==
Lung mass can be [[Classification|classified]] by location, [[histopathological]] origin, and [[imaging]] features into the following types:


Lung masses may be classified by location, histopathological origin, imaging features.


* '''Location'''
:*Pleural
:*Endobronchial
:*Parenchymal
*'''Histopathological origin'''
:*Malignant
:*Benign
*'''Imaging features'''
:*Hyperdense pulmonary mass

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:
