Overview

On chest radiography, lung hamartomas are characterized by a sharply demarcated pulmonary nodule and popcorn calcification (feature of chondroid calcifications in hamartomas).

Chest radiography (CXR) is non-specific and demonstrates soft tissue attenuation and a well-circumscribed mass with either smooth or lobulated margins.^[1]^[2]^[3]
On chest radiography, common findings of pulmonary hamartoma include:

Calcification ("popcorn pattern")
- Popcorn pattern is a reliable indicator of a benign lesion but is present in only a minority of cases^[1]
Fat: the lesion is typically of low density for its size^[4]

Frontal chest x-ray (CXR) shows a well circumscribed, smooth margin lesion in the left middle lobe.
Lateral chest x-ray (CXR) shows a well circumscribed soft tissue attenuation lesion overlapping the heart.
