Overview
On chest radiography, lung hamartomas are characterized by showing a sharply demarcated pulmonary nodule and popcorn calcifications (feature of chondroid calcifications in hamartomas).[1]
Chest X Ray
- Chest radiography (CXR) is non-specific, demonstrating a soft tissue attenuation, well-circumscribed mass with either smooth or lobulated margins.[2]
- 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[2]
- Fat, the lesion is typically of low density for its size[1]
- There are no CXR findings associated with other types of harmartoma[2]
Gallery
-
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.
