Chronic right lung atelectasis can mimic pulmonary embolism on ventilation-perfusion scans. This case highlights how prolonged atelectasis can lead to pulmonary artery hypertension, causing a false positive V/Q scan finding.

Area of Science:

  • Pulmonary medicine
  • Radiology
  • Cardiovascular imaging

Background:

  • Ventilation-perfusion (V/Q) scans are crucial for diagnosing pulmonary embolism.
  • Chronic lung conditions can present diagnostic challenges in imaging.

Observation:

  • A patient with chronic intermittent right lung atelectasis underwent V/Q imaging.
  • The V/Q scan showed a mismatch in the right lung, simulating pulmonary embolism.

Findings:

  • Pulmonary arteriogram excluded embolic disease.
  • Reduced capillary phase opacification and elevated pulmonary artery pressure were noted in the right lung.
  • These findings suggest isolated right pulmonary artery hypertension secondary to atelectasis.

Implications:

  • Prolonged atelectasis can cause secondary pulmonary hypertension.
  • This condition can lead to misinterpretation of V/Q scans, mimicking pulmonary embolism.
  • Accurate diagnosis requires correlation with other imaging modalities and clinical context.
