【摘要】：目的探討胰腺囊性腫瘤的影像學表現(xiàn)及其診斷價值。方法回顧性分析2014年1月至2015年12月浙江大學醫(yī)學院第二附屬醫(yī)院收治的95例胰腺囊性腫瘤患者臨床資料。其中男37例,女58例;年齡10~80歲,中位年齡54歲。漿液性囊性腫瘤(SCN)16例,黏液性囊性腫瘤(MCN)11例,導管內(nèi)乳頭狀黏液腫瘤(IPMN)21例,實性假乳頭狀瘤(SPN)囊變12例,胰腺神經(jīng)內(nèi)分泌腫瘤(PNEN)囊變24例,胰腺癌囊變11例�；颊呔炇鹬橥鈺�,符合醫(yī)學倫理學規(guī)定。分析胰腺囊性腫瘤患者的CT、MRI表現(xiàn)及計算其診斷準確率。結(jié)果 SCN以多發(fā)細小囊為特征。MCN以邊界清晰的厚壁單腔病灶為特征,好發(fā)于胰體尾部。IPMN以病灶與主胰管相通為特征,主胰管和分支胰管均有不同程度擴張。SPN囊變以漸進性強化為特征,但強化程度低于胰腺實質(zhì)。PNEN囊變以動脈期明顯強化為特征。胰腺癌囊變以缺乏血供并周圍組織侵犯或遠處轉(zhuǎn)移為特征。SCN的CT及MRI診斷準確率最低,分別為29%和14%;PNEN囊變CT及MRI診斷準確率最高,分別為89%和100%。結(jié)論胰腺囊性腫瘤臨床癥狀不典型,影像學檢查仍為主要診斷手段,對大多數(shù)胰腺囊性腫瘤的診斷以及良惡性的鑒別具有較高價值。
[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.
