Gallbladder adenomyomatosis: findings on MRT

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 adenomyomat osis confirmed at cholecystectomy, Results: The surgical specimen showed findings typical of adenomyomatosis, including marked thickening of both epithelial and muscular elements with m ultiple Rokitansky-Aschoff sinuses. On gadolinium-enhanced spoiled gradient -echo images and single-shot fast spin-echo images, mild gallbladder wall t hickening with multiple intramural cystic components from Rokitansky-Aschof f sinuses were readily visualized. Conclusion: Adenomyomatosis of the gallbladder can be detected and diagnose d from MRI findings.
