    Summary
    This summary is machine-generated.

    A deep lateral costophrenic angle on chest X-rays can be the sole indicator of pneumothorax. This subtle sign is crucial for accurate diagnosis in supine patients.

    Area of Science:

    • Radiology
    • Pulmonary Medicine
    • Diagnostic Imaging

    Background:

    • Pneumothorax diagnosis can be challenging, especially in supine patients.
    • Subtle radiographic findings may be overlooked.
    • Early detection is critical for patient management.

    Purpose of the Study:

    • To highlight the significance of a deep lateral costophrenic angle as a sign of pneumothorax.
    • To review cases demonstrating this specific radiographic finding.
    • To emphasize the importance of recognizing this sign for clinicians and radiologists.

    Main Methods:

    • Retrospective review of seven patient cases.
    • Analysis of supine chest radiographs.
    • Correlation of radiographic findings with clinical diagnosis.

    Main Results:

    • A deep lateral costophrenic angle was the primary radiographic indicator of pneumothorax in all reviewed cases.
    • This finding, though subtle, was consistently associated with pneumothorax.
    • The sign's utility was demonstrated across multiple cases.

    Conclusions:

    • The deep lateral costophrenic angle is a vital, albeit subtle, sign of pneumothorax on supine chest radiographs.
    • Radiologists and clinicians must be aware of this sign for timely diagnosis.
    • Recognition of this finding can improve patient outcomes by facilitating prompt treatment.
