Summary
Hyalinizing cholecystitis, a rare chronic inflammation, shows specific gallbladder wall changes. Imaging findings on 18F-FDG PET/CT and MRI aid in diagnosing this condition.
Area of Science:
- Gastroenterology
- Radiology
- Pathology
Background:
- Hyalinizing cholecystitis is an uncommon form of chronic cholecystitis.
- It is characterized by lymphoplasmacytic infiltration in the gallbladder wall.
Purpose of the Study:
- To describe the imaging findings of hyalinizing cholecystitis using 18F-FDG PET/CT and MRI.
- To highlight the importance of considering this rare entity in the differential diagnosis.
Main Methods:
- Review of 18F-FDG PET/CT findings.
- Review of MRI findings.
- Correlation with histopathological features.
Main Results:
- Gallbladder wall thickening was observed.
- Intense 18F-FDG uptake was noted on PET/CT.
- Specific patterns on MRI were identified.
Conclusions:
- Hyalinizing cholecystitis presents with characteristic imaging features.
- 18F-FDG PET/CT and MRI are valuable tools for diagnosis.
- Consider hyalinizing cholecystitis in cases of gallbladder wall thickening with high 18F-FDG uptake.
