摘要
本文总结经薄层移动式动态CT检查并经手术及病理证实的胰岛细胞瘤7例(胰岛素瘤5例、无功能胰岛细胞瘤2例),胰腺囊腺癌4例,分析其CT征象,指出典型的胰岛素瘤瘤体积较小,CT平扫为等密度,造影后明显增强,肿块多位于胰尾部,肿瘤直径多为1.0cm-2.5cm。无功能胰岛细胞瘤体积较大,有完整包膜。胰腺囊腺瘤肿块大小不等,多为结节状及分叶状,有完整的纤维包膜。典型的CT表现为:平扫为有小分叶的低密度灶,CT值略高于囊肿,内有放射状细小等密度分隔,中央可见小钙化灶,造影后肿瘤分隔及包膜增强,边缘锐利。
CT scans of 11 Pathologically proved Pancreatic benign neoplasms (7 islet cell tumors, 4 cystadenomas)were reviewed. Typical CT findings of islet - cell tumor were small mass appearing as isoattenuation with nonenhanced CTand prominent hyperattenuation with contrastenhanced CT. Cystadenomas were hypoattenuation mass with multiple sepationsand central calcification.
