发布时间：2018-08-06 17:03
【摘要】：目的探讨胰腺囊性肿瘤的影像学表现及其诊断价值。方法回顾性分析2014年1月至2015年12月浙江大学医学院第二附属医院收治的95例胰腺囊性肿瘤患者临床资料。其中男37例,女58例;年龄10~80岁,中位年龄54岁。浆液性囊性肿瘤(SCN)16例,黏液性囊性肿瘤(MCN)11例,导管内乳头状黏液肿瘤(IPMN)21例,实性假乳头状瘤(SPN)囊变12例,胰腺神经内分泌肿瘤(PNEN)囊变24例,胰腺癌囊变11例。患者均签署知情同意书,符合医学伦理学规定。分析胰腺囊性肿瘤患者的CT、MRI表现及计算其诊断准确率。结果 SCN以多发细小囊为特征。MCN以边界清晰的厚壁单腔病灶为特征,好发于胰体尾部。IPMN以病灶与主胰管相通为特征,主胰管和分支胰管均有不同程度扩张。SPN囊变以渐进性强化为特征,但强化程度低于胰腺实质。PNEN囊变以动脉期明显强化为特征。胰腺癌囊变以缺乏血供并周围组织侵犯或远处转移为特征。SCN的CT及MRI诊断准确率最低,分别为29%和14%;PNEN囊变CT及MRI诊断准确率最高,分别为89%和100%。结论胰腺囊性肿瘤临床症状不典型,影像学检查仍为主要诊断手段,对大多数胰腺囊性肿瘤的诊断以及良恶性的鉴别具有较高价值。
[Abstract]:Objective to investigate the imaging features and diagnostic value of pancreatic cystic tumors. Methods from January 2014 to December 2015, the clinical data of 95 patients with pancreatic cystic tumor treated in the second affiliated Hospital of Zhejiang University Medical College were retrospectively analyzed. Among them, 37 cases were male and 58 cases were female, the age was 1080 years old, the median age was 54 years old. There were 16 cases of serous cystic tumor (SCN), 11 cases of mucinous cystic tumor (MCN), 21 cases of intraductal papillary mucinous tumor (IPMN), 12 cases of solid pseudopapillary tumor (SPN), 24 cases of pancreatic neuroendocrine tumor (PNEN) and 11 cases of pancreatic carcinoma. All patients signed informed consent, in accordance with the provisions of medical ethics. Ct MRI findings of pancreatic cystic tumors were analyzed and the diagnostic accuracy was calculated. Results SCN was characterized by multiple small cysts. MCN was characterized by a thick-walled single-lumen lesion with clear boundary, and was characterized by communicating between the lesion and the main pancreatic duct in the tail of the pancreas. Both the main pancreatic duct and the branched pancreatic duct were characterized by progressive enhancement, but the enhancement degree was lower than that of pancreatic parenchyma. PNEN cystic degeneration was characterized by obvious enhancement in arterial phase. The diagnostic accuracy of CT and MRI was the lowest in the cases of pancreatic cancer cystic lesions characterized by lack of blood supply and invasion of surrounding tissues or distant metastasis. The diagnostic accuracy of CT and MRI were 29% and 14% respectively, 89% and 100%, respectively. Conclusion the clinical symptoms of pancreatic cystic tumors are not typical and the imaging examination is still the main diagnostic method. It has a high value in the diagnosis of most pancreatic cystic tumors and the differential diagnosis of benign and malignant tumors.
