Overview

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

Chest X Ray

  • 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][4][5]
  • 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[6]
  • There are no CXR findings associated with other types of harmartomas[1]
