False-negative gallbladder scintigram in acute cholecystitis

R A Echevarria, J L Gleason

    Journal of Nuclear Medicine : Official Publication, Society of Nuclear Medicine
    |September 1, 1980
    PubMed
    Summary

    Hepatobiliary scintigraphy visualized the gallbladder in two acute cholecystitis cases. However, this imaging alone cannot rule out non-calculous causes of gallbladder inflammation.

    Area of Science:

    • Gastroenterology
    • Nuclear Medicine
    • Diagnostic Imaging

    Background:

    • Acute cholecystitis, commonly caused by gallstones obstructing the cystic duct, presents a diagnostic challenge.
    • Hepatobiliary scintigraphy is a key imaging modality for evaluating gallbladder function and detecting cholecystitis.

    Observation:

    • Two cases of acute cholecystitis were identified where the gallbladder was successfully visualized during hepatobiliary scintigraphy.
    • This visualization occurred despite the presence of acute inflammation.

    Findings:

    • While gallstone-induced obstruction is the predominant cause, a subset of acute cholecystitis cases arise from alternative pathogenic mechanisms.
    • The presence of gallbladder visualization on scintigraphy does not exclude these non-calculous etiologies.

    Implications:

    • Hepatobiliary scintigraphy findings require careful interpretation in the context of suspected acute cholecystitis.
    • Further diagnostic evaluation may be necessary to definitively exclude non-calculous causes of gallbladder inflammation, guiding appropriate clinical management.
