2种胰腺良性病变的^18F—FDGPET／CT诊断辨析

Differential diagnosis and analysis of two kinds of benign pancreatic lesions by 18F-FDG PET/CT

胰腺病变种类繁多，主要分为以外分泌腺肿瘤、内分泌腺肿瘤、间质来源肿瘤为代表的肿瘤性疾病和以胰腺真、假性囊肿等为代表的非肿瘤性病变。鉴于不同疾病影像学表现复杂多样，笔者选取了临床工作中易误诊的两个病种进行分析讨论，即IgG4相关硬化性胰腺炎和胰腺假性囊肿，并分别从临床特点、常规影像学特征及18F-FDGPET／CT影像学特征等多方面进行诊断辨析，以期为临床诊断提供帮助。

There are a wide variety of pancreatic lesions, which are mainly classified as neoplastic lesions, such as exocrine gland tumors, endocrine tumors, and mesenchymal tumors, etc. and non-neoplastic lesions which include pancreatic pseudocysts, pancreatic cysts, etc. In view of the complex and diversified imaging features of different pancreatic diseases, the author selected two kinds of diseases that are often misdiagnosed in clinical work to analyze and discuss： IgG4-related sclerosing pancreatitis and pancreatic pseudocyst. We analyzed and discriminated from the clinical features, conventional imaging features and 18F-FDG PET/CT imaging features respectively, to provide clinical help.
