Gallbladder adenomyomatosis: findings on MRI.
BACKGROUND
To describe the characteristic magnetic resonance imaging (MRI) findings of gallbladder adenomyomatosis in two cases.


METHODS
Two patients had abdominal MRI findings of gallbladder adenomyomatosis confirmed at cholecystectomy.


RESULTS
The surgical specimen showed findings typical of adenomyomatosis, including marked thickening of both epithelial and muscular elements with multiple Rokitansky-Aschoff sinuses. On gadolinium-enhanced spoiled gradient-echo images and single-shot fast spin-echo images, mild gallbladder wall thickening with multiple intramural cystic components from Rokitansky-Aschoff sinuses were readily visualized.


CONCLUSIONS
Adenomyomatosis of the gallbladder can be detected and diagnosed from MRI findings.
