【摘要】：目的:探讨胰腺导管内乳头状黏液性肿瘤(IPMN)的CT影像特征,重点研究重度异性增生IPMN的CT特征。资料与方法:本研究搜集并回顾分析了39例IPMN患者的临床资料、病理资料及CT影像表现,运用统计学方法分析重度异型增生IPMN与轻-中度异型增生IPMN患者及浸润性癌患者的CT影像学差异。结果 :重度异型增生IPMNs的CT影像表现部分与浸润性癌类似,提示有一定的恶性倾向(囊壁增厚、壁内结节、囊壁及结节强化);部分与轻-中度异型增生IPMN类似,提示有一定的良性倾向(较少出现胰腺周围渗出及淋巴结肿大)。结论:重度异型增生IPMN的CT表现介于轻-中度异型增生IPMN及浸润性癌两组间,具有一定特征。因其特殊的影像特征,临床上对于重度异性IPMN更需引起足够重视。
[Abstract]:Objective: to investigate the CT features of intraductal papillary mucinous neoplasms of the pancreas (IPMN), and to study the CT features of severe dysplastic IPMN. Materials and methods: the clinical data, pathological data and CT findings of 39 patients with IPMN were collected and analyzed retrospectively. The CT imaging differences of severe dysplasia (IPMN), mild to moderate dysplasia (IPMN) and invasive carcinoma were analyzed by statistical method. Results: the CT findings of severe dysplasia IPMNs were similar to those of invasive carcinoma, suggesting that there were some malignant tendencies (cystic wall thickening, intramural nodules, cystic wall and nodular enhancement), and some of them were similar to mild to moderate dysplasia IPMN. It suggests that there is a certain benign tendency (there is less peripancreatic exudation and lymph node enlargement. Conclusion: the CT features of severe dysplasia IPMN are between mild and moderate dysplasia IPMN and invasive carcinoma. Due to its special imaging features, it is necessary to pay more attention to severe heterosexual IPMN clinically.
