胰岛素瘤的MSCT诊断(附16例报告)

MSCT Diagnosis of Insulinoma (a Report of 16 cases)

目的:探讨胰岛素瘤的MSCT表现。方法:对16例经病理证实的胰岛素瘤MSCT表现进行回顾性分析。结果:CT扫描1例未发现病灶。胰岛素瘤CT平扫:大多数表现为等密度,1例为高密度,1例为囊实性。增强扫描:实体部分均有强化。11例动脉期强化程度高于门脉期;4例门脉期强化程度高于动脉期;延迟扫描强化程度均有减退。结论:胰岛素瘤的CT表现具有一定的特征性,MSCT有助于病变的显示。

Objective： To evaluate the MSCT findings of insulinoma. Methods： lmaging findings in 16 patients with pathlogically proven insulinoma were analyzed retrospectively. Results： Lesion was not detected in 1 case. In plain CT scan, most of the tumors showed isodensity, 1 case showed high density, 1 case contained hoth solid and cystic components. Solid part in tumor showed marked enhancement. The degree of enhancement was higher in arterial than in portal venous phase in 11 cases. 4 cases showed conversely, The degree of enhancement all fell in delay phase. Conclusion：Insulinoma has comparatively characteristic imaging features. MSCT can help diagnose.
