Pseudoinfiltrates on chest x-ray

Overview

Pseudoinfiltrates are chest x-ray findings that may be mistaken for lung lesions

Causes

  • Poor inspiration — Crowding of lung marking at the lung bases
  • Poor positioning — scapula overlap, rotation
  • Lower lobe pulmonary arteries — On PA and lateral radiographs
  • Vascular anomalies — e.g. Scimitar sign (anomalous pulmonary venous return)
  • Pleural lesions — e.g. plaques, mesothelioma, scarring
  • Overlying soft tissue — Breast, pectoralis muscle, chest wall lesions, nipples
  • Skeletal lesions — Vertebral body osteophyte, healed rib fracture, crossing ribs, calcified costal cartilage
  • Prostheses and clothing — Breast implants, buttons, plombage
