    Summary
    This summary is machine-generated.

    Plain abdominal X-rays showing a tubular shadow over the liver may indicate air in the bile ducts. However, surrounding fat can mimic this finding, requiring further imaging for accurate diagnosis.

    Area of Science:

    • Radiology
    • Gastroenterology
    • Medical Imaging

    Background:

    • Plain abdominal radiographs can reveal lucent tubular shadows over the liver.
    • These shadows are often interpreted as pneumobilia, indicating air within the biliary tree.

    Purpose of the Study:

    • To differentiate true pneumobilia from pseudopneumobilia caused by periductal fat.

    Main Methods:

    • Review of abdominal plain films.
    • Comparison with findings from intravenous cholangiography.

    Main Results:

    • A lucent tubular shadow on plain films can suggest pneumobilia.
    • Normal periductal fat can mimic pneumobilia.
    • Intravenous cholangiography is effective in confirming the diagnosis.

    Conclusions:

    • Distinguishing between true pneumobilia and artifactual findings is crucial for accurate diagnosis.
    • Intravenous cholangiography is a valuable tool for confirming pneumobilia.
