Round atelectasis: another pulmonary pseudotumor

P Stark

    The American Review of Respiratory Disease
    |February 1, 1982

    Summary
    This summary is machine-generated.

    Round atelectasis is a rare lung condition often linked to pleural abnormalities. Recognizing its distinct comet-tail sign can prevent unnecessary invasive medical procedures.

    Area of Science:

    • Pulmonology
    • Radiology
    • Thoracic Medicine

    Background:

    • Round atelectasis is an uncommon form of lung collapse.
    • It is frequently associated with pleural thickening, effusions, or plaques.

    Observation:

    • The condition presents as a subpleural mass.
    • A characteristic 'comet-tail' sign is observed on imaging.

    Findings:

    • The 'comet-tail' sign is a key diagnostic feature.
    • This sign represents infolded visceral pleura and trapped lung parenchyma.

    Implications:

    • Accurate identification of round atelectasis can prevent misdiagnosis.
    • Recognition avoids the need for unnecessary invasive diagnostic procedures, such as biopsies.
  • This improves patient management and reduces healthcare costs.
