Sonography of tumefactive biliary sludge

J Fakhry

    Summary

    Biliary sludge can mimic gallbladder masses on ultrasound. Recognizing this pseudotumor appearance is crucial for accurate diagnosis and avoiding unnecessary procedures.

    Area of Science:

    • Gastroenterology
    • Diagnostic Imaging
    • Hepatobiliary Medicine

    Background:

    • Gallbladder abnormalities can present as masses on imaging.
    • Biliary sludge is a common finding, but its appearance can vary.
    • Misinterpretation of gallbladder findings can lead to misdiagnosis.

    Purpose of the Study:

    • To report on a specific presentation of biliary sludge.
    • To differentiate sludge from true gallbladder masses.
    • To improve diagnostic accuracy in gallbladder imaging.

    Main Methods:

    • Retrospective review of five patient cases.
    • Ultrasound examination of the gallbladder.
    • Follow-up imaging and surgical correlation.

    Main Results:

    • Low-amplitude echoes mimicking a mass were observed in the gallbladder lumen in five patients.
    • In four patients, the 'mass' resolved on repeat ultrasound.
    • Surgical confirmation in one patient identified biliary sludge as the cause.

    Conclusions:

    • Biliary sludge can present as a tumefactive pseudotumor within the gallbladder.
    • Awareness of this presentation aids in avoiding misinterpretation of gallbladder ultrasound findings.
    • This knowledge can prevent unnecessary interventions for benign sludge collections.
