    A normal variant fold in the gallbladder can mimic a polyp or calculus on ultrasound scans. Recognizing this anatomical variation and using proper scanning techniques can prevent misdiagnosis.

    Area of Science:

    • Medical Imaging
    • Gastroenterology
    • Anatomy

    Background:

    • Gallbladder imaging frequently encounters anatomical variations.
    • Accurate interpretation of gallbladder ultrasound (cholecystosonography) is crucial for diagnosis.

    Purpose of the Study:

    • To describe a specific gallbladder fold variant.
    • To highlight potential diagnostic pitfalls in cholecystosonography.
    • To emphasize the importance of recognizing normal variants.

    Main Methods:

    • Retrospective review of three cholecystosonography cases.
    • Analysis of imaging findings on supine scans.
    • Correlation with anatomical knowledge of the gallbladder.

    Main Results:

    Related Experiment Videos

    • A fold along the posterior gallbladder wall at the body-infundibulum junction was observed.
    • This fold was misinterpreted as a small polyp in one case.
    • The same fold was misidentified as a calculus in two cases.

    Conclusions:

    • This posterior gallbladder wall fold is a normal anatomical variant.
    • Familiarity with this variant can reduce misdiagnosis of polyps and calculi.
    • Correct ultrasound scanning methodology is essential for accurate gallbladder assessment.
