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.
