目的 探讨胆囊腺瘤(GA)的多层 螺旋CT(MSCT)表现，以提高对GA诊断的准 确率。方法 回顾性分析经临床术后病理 证实8例GA的MSCT表现，所有病例均进行 CT平扫及三期增强扫描。结果 本组病例 中7例单发，6例位于胆囊体部，1例位于 胆囊底部；1例多发(3枚)，分别位于胆囊 底、体部；2例癌变。8例GA10枚病灶中， 分叶状6枚，类圆形4枚；宽基底7枚，窄 基底3枚。病灶直径约0.8-2.3cm；2枚癌 变病灶直径大于2.0cm，邻近胆囊壁不均 匀增厚。CT平扫呈等、低密度，CT值约 23-47HU；三期增强扫描9枚病灶中度及明 显强化，以门脉期强化较显著，强化范围 在48-102HU之间，其内无出血、坏死及钙 化。结论 GA的MSCT表现具有一定的特征 性，认识这些特点有助于提高诊断准确 率。

Objective To explore the MSCT manifestations of gallbladder adenoma(GA),to further improve the accuracy of diagnosis. Methods The MSCT manifestations of 8 cases with GA Confirmed by postoperative pathology were analyzed retrospectively, CT precontrast scanning and three phases contrast enhanced scanning were performed in all cases. Results 7 cases were single in the cases,6 cases were located in the body of gallbladder, 1 case in the bottom. 1 case were multiple (3 lesions), Lesions respectively located in the bottom and the body of the gallbladder. 2 cases were malignant transformation. Among 10 lesions of 8 cases,6 lesions were lobulated, 4 lesions were nearly round. 7 lesions were broad-based interface, 3 lesions were narrow-based interface.Lesions were about 0.8-2.3cm in diameter. 2 lesions of malignant transformation is greater than 2.0 cm in diameter, irregular thickening of gallbladder wall adjacent to lesions. Lesions show isodensity or low density on CT pre-contrast scanning, ranged from about 23-47 HU. By three phases contrast enhanced scanning, 9 lesions show moderate and significant enhancement, more significant in portal vein phase, ranged from about 48-102HU, no hemorrhage,necrosis and calcification in the lesion. Conclusion The MSCT performance of GA has a certain characteristic, understanding these features help to improve the diagnostic accuracy.
