    Cholescintigraphy findings in gallbladder carcinoma can mimic acute cholecystitis or cholelithiasis. Nonvisualization of the gallbladder with normal transit was seen in four patients, with some showing masses or metastasis.

    Area of Science:

    • Gastroenterology
    • Diagnostic Imaging
    • Oncology

    Background:

    • Gallbladder carcinoma is a rare but aggressive malignancy.
    • Distinguishing gallbladder carcinoma from benign gallbladder disease on imaging can be challenging.
    • Cholescintigraphy is a functional imaging technique used to evaluate the hepatobiliary system.

    Purpose of the Study:

    • To describe the cholescintigraphy findings in patients with gallbladder carcinoma.
    • To assess the diagnostic utility of cholescintigraphy in identifying gallbladder cancer.
    • To compare scintigraphic findings of gallbladder carcinoma with those of benign gallbladder conditions.

    Main Methods:

    • Retrospective analysis of five patients diagnosed with gallbladder carcinoma.
    • Review of cholescintigraphy (hepatobiliary iminodiacetic acid scan) findings.

  • Correlation of imaging findings with clinical presentation and pathology.

    • Main Results:

    • Four patients with gallbladder carcinoma presented with nonvisualization of the gallbladder on cholescintigraphy, similar to acute cholecystitis.
    • Normal hepatoenteric transit time was observed in these four patients.
    • One patient showed a large portal mass, and two had liver metastases.
    • The fifth patient presented with jaundice and complete biliary obstruction, indicated by absent bowel activity.

    Conclusions:

    • Cholescintigraphy findings in gallbladder carcinoma can overlap significantly with those of cholelithiasis and cholecystitis.
    • Nonvisualization of the gallbladder on cholescintigraphy, even with normal transit, warrants further investigation for malignancy.
    • Clinical and scintigraphic features alone may not reliably differentiate gallbladder cancer from benign inflammatory conditions.
