MSCT diagnosis of gallbladder adenomyomatosis

Objective: To investigate the diagnostic value of multi-slice CT for gallbladder adenomyomatosis. Methods: Seventeen patients who underwent 64-slice CT had histologically confirmed gallbladder adenomyomatosis. The thin axial and multiplanar reconstructed images were retrospectively analyzed. Results: Of 17 patients, 6 were diffuse, 6 were fundal, 5 were focal. Twelve patients were diagnosed correctly before surgery. CT showed diffuse or focal gallbladder wall thickening with homogeneous, heterogeneous, or ring enhancement. There were multiple Rokitansky-Aschoff sinuses in the gallbladder wall with garland sign. Conclusions: The thin axial and multiplanar reconstructed CT can display the Rokitansky-Aschoff sinuses and is valuable for diagnosing gallbladder adenomyomatosis. (authors)
