Liver scanning and the intrahepatic gallbladder: Case report.
Summary
Nonspecific hepatic focal defects on 99mTc-sulfur colloid imaging can obscure diagnosis. This case highlights ectopic gallbladder diagnosis using cholecystography and 131I-rose bengal in a patient with cirrhosis and suspected liver cancer.
Area of Science:
- Nuclear medicine
- Diagnostic imaging
- Hepatology
Background:
- Hepatic focal defects on technetium-99m sulfur colloid imaging are often nonspecific.
- Differentiating these defects from intrahepatic neoplasms can be challenging.
Observation:
- A patient with cirrhosis and suspected intrahepatic neoplasm presented with nonspecific hepatic focal defects on imaging.
- Cholecystography and iodine-131 rose bengal studies were employed for further investigation.
Findings:
- Ectopic gallbladder was successfully localized using cholecystography and 131I-rose bengal scintigraphy.
- These findings aided in clarifying the nature of the hepatic focal defects.
Implications:
- This case demonstrates the utility of specific imaging modalities for diagnosing ectopic gallbladder in complex hepatic cases.
- Accurate diagnosis of ectopic gallbladder is crucial for appropriate patient management and treatment planning.
