Overview

CT scan is the method of choice for the evaluation of lung mass. On CT scan, characteristic findings of lung mass include single pulmonary nodule or mass with localized area of parenchymal consolidation and bubble-like areas of low attenuation within the lung mass (characteristic finding).

CT scan

CT scan is the method of choice for the evaluation of lung mass. The evaluation of lung mass will depend on several characteristics such as calcification, margins, location, distribution, and attenuation. On CT scan, characteristic findings of lung mass, include:

Single pulmonary nodule or mass
Localized area of parenchymal consolidation
Bubble-like areas of low attenuation within the lung mass (characteristic finding)
Hilar and mediastinal lymphadenopathy is uncommon
Persistent peripheral consolidation

Squamous cell lung carcinoma: Peripheral squamous cell lung carcinoma may be seen as a solid nodule/mass with or without an irregular border. The irregular margin can be attributed to a desmoplastic reaction or infiltrative growth
