胰腺神经内分泌肿瘤的MDCT表现

目的:探讨胰腺神经内分泌肿瘤在MDCT扫描的影像表现。方法:回顾性分析经手术后病理证实的24例均为单发的NETP的CT平扫及三期增强表现。结果:24例肿瘤其中位于胰头4例、胰颈4例、胰体8例、胰腺体尾部8例,肿块最大者大小约9.5cm×13.5cm×15cm,最小直径约1.8cm。神经内分泌瘤8例,神经内分泌癌16例。增强后明显均匀强化5例,强化程度高于胰实质,且边界清楚。增强后不均匀强化19例,其中2例可见肿瘤内有钙化,8例可见低密度坏死区和囊变,5例胰管明显扩张。结论:动态增强扫描强化程度、强化方式及CT图像征象有助于胰腺神经内分泌肿瘤与胰腺其他肿瘤性疾病的鉴别,对术前分期及评估有着较高的价值。

Imaging of Neuroendocrine Tumors of the Pancreas in the MDCT

Objective：Discuss of the imaging features neuroendocrine Tumors of the Pancreas in the value of MDCT. Methods： Retrospective analysis of postoperative pathology confirmed through 24 patients are the single NETP CT plain and enhanced performance and three phase. Results： 24 cases of pancreatic head tumor located in 4 cases of pancreatic neck 4 cases of pancreatic body 8 cases of pancreatic tail 8 cases. The maximum tumour size 9.5cm×l3.5cm×15cm, minimum diameter 1. 8cm. Pancreatic neuroendocrine tumour 8 cases＇ pancreatic neuroendocrine carcinoma 16 cases. The enhanced obviously uniform reinforcement in 5 patients. Stren4gthen the level higher than pancreatic substance and boundary clear. The enhanced uneven strengthen 19 cases, among them, 2 cases were visible tumor calcification, eight cases of visible low density necrotic area and cystic change, 5 cases of pancreatic duct obvious expansion. Conclusion： Dynamic enhanced scan reinforcement degree strengthening methods and CT image signs help pancreatic neuroendocrine tumor of pancreas and other identification of neoplastic disease, for preoperative staging and evaluation has a higher value.
