Crossing Chest Wall

This feature suggests that the lesion is not intrathoracic. It should be in the chest wall. This example is braid. Sheets also can give linear shadows and should not be mistaken for a lung lesion.

Broad linear shadow in right upper lung field:

  • Not corresponding to fissure
  • Shadow can be seen to projecting beyond lung fields
  • Metallic object
