目的探讨胆囊腺瘤(AG)及腺瘤样病变的CT表现与病理特点。方法将本院2011年1月至2012年9月收治的20例胆囊腺瘤及腺瘤样病变病患作为研究对象,经手术治疗并行CT图像鉴别,对胆囊腺瘤及腺瘤样病变的CT表现与病理特点进行总结分析。结果本研究20例病患中,有4例乳头状腺瘤、5例管状腺瘤、6例腺瘤样息肉及5例乳头状-管状腺瘤;其中单发病理有14例,2个病灶者有4例,3个病灶者有2例。采用CT平扫后可知20例病患均为软组织密度,其外形呈现一种乳头状或者椭圆形;内部密度均匀,AG直径在10mm及以上的病患有12例,低于10mm的有8例;病变有5例位于胆囊颈部、6例位于胆囊底部、9例位于胆囊体部;平扫时CT值为30～44HU,当增强后CT值则为58～119HU;此外,有7例属于合并胆囊结石病患。肿瘤内部没有钙化、出血及囊变;病灶的边界十分清晰,邻近的胆囊壁结构十分完整。结论胆囊腺瘤及腺瘤样病变的CT表现有着自身的特征,为了便于鉴别肿瘤的良性与恶性,可以采用增强扫描的方式,临床上有着非常好的效果,故而值得推广及应用。
Objective To investigate the CT features and pathological features of gallbladder adenoma (AG) and adenomatous lesions. Methods Twenty patients with gallbladder adenoma and adenoma-like lesions who were treated in our hospital from January 2011 to September 2012 were selected as the research object. After the CT images were differentiated by surgical treatment, CT findings of gallbladder adenoma and adenomatous lesions CT Performance and pathological characteristics of the summary analysis. Results Among the 20 patients in our study, there were 4 papillary adenomas, 5 tubular adenomas, 6 adenomatous polyps and 5 papillary-tubular adenomas. Among them, 14 had single pathology and 2 had focal lesions There are 4 cases, 3 lesions in 2 cases. CT scan showed that 20 patients were soft tissue density, the appearance of a papillary or oval; internal density, AG diameter of 10mm and above in patients with 12 cases, less than 10mm in 8 cases ; Lesions in 5 cases located in the gallbladder neck, 6 cases located in the bottom of the gallbladder, 9 cases located in the gallbladder body; CT scan value of 30 ~ 44HU, enhanced CT value of 58 ~ 119HU; In addition, Patients with gallstone disease. No tumor within the calcification, bleeding and cystic lesions; border of the disease is very clear, the adjacent structure of the gallbladder wall is very complete. Conclusions The CT features of gallbladder adenoma and adenomatous lesions have their own characteristics. In order to facilitate the differential diagnosis of benign and malignant tumors, enhanced scanning can be used and has very good clinical results. Therefore, it is worth popularizing and applying.
