Overview
On CXR, hamartomas are characterized by showing a sharply demarcated pulmonary nodule and popcorn calcifications (feature of chondroid calcifications in hamartomas). This pattern is a reliable indicator of a benign lesion but is present in only a minority of cases.[1]
Chest X Ray
Chest radiography is non-specific, demonstrating a soft tissue attenuation, well-circumscribed mass with either smooth or lobulated margins. Calcification (classically popcorn type) may be seen, which can suggest the diagnosis. Fat is difficult to identify with certainty, although the lesion is typically of low density for its size.[1]
