摘　　要：目的探讨胆囊腺肌增生症的CT和MRI表现特点,提高诊断正确性。方法回顾性分析我院2011年8月至2014年3月34例经病理检查证实的胆囊腺肌瘤病(adenomyomatosis of gallbl-adder,GBA)患者的CT和MRI资料。结果本组行CT检查34例,其中术前确诊为GBA 25例,诊断为慢性胆囊炎5例,漏诊4例;行MRI检查20例,其中术前确诊为GBA 17例,诊断为慢性胆囊炎3例。CT及MRI平扫表现为胆囊壁弥漫性或局限性增厚,部分腔内、外面毛糙不整。增强表现为动脉期黏膜强化,门静脉期强化范围进展,延迟期持续强化,罗-阿氏窦腔内无强化。结论 CT与MRI对胆囊腺肌瘤病有较高的诊断价值,而罗阿氏窦的显示可作为定性的主要诊断依据。Objective To explore the characteristics of CT and MRI imaging in adenomyomatosis of the gallbladder and to improve the diagnotic accuracy.Methods Retrospective analysis of MRI and CT data in GBA patients from Aug.2011 to Mar.2014 in our hospital,34 cases were confirmed by pathological examination in patients.Results Thirty-four cases underwent CT examination,25 cases were diagnosed preoperatively,4 cases misdiagnosed as chronic cholecystitis,4 cases misdiagnosed;20 cases underwent MRI examination,including 17 cases diagnosed preoperatively,3 cases diagnosis as chronic cholecystitis.CT and MRI findings were that segmental or diffuse gallbladder wall thicken,partly coarse in and outside of the wall.On enhanced images,the lesions showed mucosa enhancement at arterial phase,and continued to enhance at portal venous phase and delay phase,the RA sinus cavity without enhancement.Conclusion CT and MRI may play an important role in diagnosis of GBA,Argyu Robertson＇s sinuses may be the typical sign for diagnosis basis.
