目的探讨胆囊腺肌瘤病(GBA)的VCT表现,以期提高对该病的诊断准确率。方法搜集2006年10月—2011年2月本院有完整VCT资料并经手术病理证实的60例GBA病例,60例患者均行VCT平扫及增强扫描,结合文献资料回顾性分析其CT表现。结果 60例均显示胆囊壁弥漫或局限明显增厚,黏膜面强化程度高于浆膜面,延迟期扫描胆囊壁内可见与胆囊腔相通的RAS。CT正确诊断弥漫型18例,节段型16例,基底型(局限型)26例,7例弥漫型术前误诊为慢性胆囊炎和黄色肉芽肿性胆囊炎,6例基底型误诊为胆囊癌。结论 VCT表现在诊断GBA中有特征性,可以作为该病术前诊断的有效方法。
Objective To investigate the VCT manifestations of gingival adenomyoma (GBA) in order to improve the diagnostic accuracy of the disease. Methods Sixty cases of GBA with complete VCT data confirmed by surgery and pathology in our hospital from October 2006 to February 2011 were collected. All 60 patients underwent VCT plain scan and enhanced scan. The CT findings were retrospectively analyzed with literature data. Results All 60 cases showed diffuse or localized gallbladder wall thickening, mucosal surface enhanced higher than the serosal surface, the delayed scan of the gallbladder wall can be seen with the gallbladder cavity connected RAS. CT correct diagnosis of diffuse 18 cases, segmental 16 cases, 26 cases of basal (localized), 7 cases of diffuse preoperative misdiagnosis of chronic cholecystitis and granulomatous yellow cholecystitis, 6 cases of misdiagnosed as gallbladder cancer of the basal type . Conclusions VCT is characteristic in the diagnosis of GBA and can be used as an effective method for preoperative diagnosis.
