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 type")
  • "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]
