Background: Gallbladder adenomyomatosis is a classical but seldom recognized cause of gallbladder wall thickening. The purpose of this study was to review the imaging features of this disease and emphasize the diagnostic value of ultrasonography. Methods: Sonographs taken of thickened lesions of the gallbladder wall in 21 patients were examined to correlate clinical, ultrasonographic and pathological characteristics. Results: Ultrasonographic abnormalities that correlated to pathologic findings of gallbladder adenomyomatosis were found in all 21 patients. Histologically, the distinctive features were proliferation of the epithelia and/or formation of outpouchings of the mucosa into or through the muscularis, which, in some cases, formed diverticula (Rokitansky-Aschoff sinuses). Of the 21 patients, eight (38%) had generalized type, nine (43%) had segmental type and four (19%) had localized type adenomyomatosis. Conclusion: The ultrasonographic characteristics of gallbladder adenomyomatosis include generalized or segmental thickening of the gallbladder wall with intramural diverticula, which may be echo-free and/or highly reflective. These results confirm the value of ultrasonography in diagnosing gallbladder adenomyomatosis and its routine use is recommended.
