    Nonvisualization of the gallbladder during hepatobiliary scintigraphy is not specific for acute cholecystitis. This study reports the first case of gallbladder neoplasm causing nonvisualization, expanding the differential diagnosis.

    Area of Science:

    • Nuclear medicine
    • Diagnostic imaging
    • Gastroenterology

    Background:

    • Hepatobiliary scintigraphy using Tc-99m iminodiacetic acid derivatives is a standard diagnostic tool.
    • Nonvisualization of the gallbladder on these scans typically suggests acute cholecystitis.

    Observation:

    • This report details a rare case where gallbladder neoplasm mimicked acute cholecystitis on Tc-99m iminodiacetic acid derivative imaging.
    • The patient presented with nonvisualization of the gallbladder, a finding usually attributed to acute or chronic cholecystitis.

    Findings:

    • Gallbladder neoplasm was identified as the cause of nonvisualization, representing a novel differential diagnosis.
    • This finding highlights that gallbladder nonvisualization is not pathognomonic for cholecystitis.

    Implications:

    • Clinicians should consider rare causes like neoplasm in the differential diagnosis of gallbladder nonvisualization.
    • This case expands the understanding of imaging findings in gallbladder pathology and informs diagnostic strategies.
