摘　　要：目的根据胆囊腺肌增生症的CT表现,探讨多层螺旋CT对本病的诊断及鉴别诊断价值。方法回顾性分析17例经手术病理证实的胆囊腺肌增生症病例,16例行CT平扫及增强扫描,采用64排CT扫描,用薄层重组及多平面重组,观察病变的细节显示。结果 17例患者中,弥漫型6例,基底局限型6例,节段型5例。术前诊断正确12例,CT表现为胆囊壁广泛性或局限性增厚,增厚囊壁内可见多发罗-阿氏窦,典型表现为"花环征"。CT增强扫描病变区明显均匀强化或者不均匀强化,罗-阿氏窦边缘环状强化。结论 64排CT对胆囊腺肌增生症的诊断及鉴别诊断有较高的价值,薄层重组及多平面重组有利于对罗-阿氏窦的显示,而罗-阿氏窦的显示则具有定性诊断的价值。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 muhiplanar 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 muhiplanar reconstructed CT can display the Rokitansky-Aschoff sinuses and is valuable for diagnosing gallbladder adenomyomatosis.
