Area of Science:

Hepatobiliary imaging
Diagnostic nuclear medicine

Background:

Morphine-augmented cholescintigraphy is a standard diagnostic tool for acute cholecystitis.
The procedure relies on gallbladder visualization following morphine administration.

Observation:

This case report presents an infrequent false-negative result using morphine-augmented cholescintigraphy for acute cholecystitis.
An apparent ectopic gallbladder was noted, presenting an unusual anatomical variation.

Findings:

False-negative results, though rare, can occur in morphine-augmented cholescintigraphy.
Gallbladder ectopia represents a significant anatomical anomaly that can impact imaging interpretation.

Implications:

Awareness of potential false-negatives is crucial for accurate diagnosis and patient management.
