False negative angiogram in pulmonary embolism.

L Price

    Summary
    This summary is machine-generated.

    A pulmonary embolism was suspected based on symptoms and scan results, but a standard pulmonary angiogram was normal. This case highlights the need to improve pulmonary angiography techniques to avoid false negatives.

    Area of Science:

    • Radiology
    • Cardiovascular Imaging
    • Pulmonary Medicine

    Background:

    • Pulmonary embolism (PE) is a potentially life-threatening condition often diagnosed using imaging techniques.
    • Accurate diagnosis of PE is crucial for timely and effective treatment.

    Observation:

    • A 19-year-old woman presented with symptoms suggestive of pulmonary infarction and an abnormal lung perfusion scan.
    • The perfusion scan findings were consistent with a pulmonary embolism.

    Findings:

    • A pulmonary angiogram, a standard diagnostic tool, was performed using a conventional technique with two bolus injections and multiple cut films.
    • The pulmonary angiogram was reported as normal, failing to detect the suspected pulmonary embolism.

    Implications:

    • This case demonstrates a false-negative result from a conventional pulmonary angiogram.
    • It underscores the critical need for modifications in pulmonary angiography techniques to enhance diagnostic accuracy for pulmonary embolism.
