摘　　要：本研究总结分析了54例IgG4相关性自身免疫性胰腺炎(IgG4-AIP)患者的超声造影表现,男40例,女14例,年龄26~76(59.1±10.2)岁。结果发现IgG4-AIP的超声造影增强模式呈多样化,有部分AIP患者尤其是肿块型AIP患者在疾病初期的超声造影表现与胰腺癌的超声造影表现有类似,在增强早期、增强晚期和延迟期均会有不同程度的低增强表现,因此仅靠超声造影表现对其进行鉴别诊断是不可取的,应综合评估。To analyze and summarize the contrast-enhanced ultrasound(CEUS)characteristics in patients with IgG4 related autoimmune pancreatitis(IgG4-AIP).A total of 54 patients(aged 26 to 76 years old)with IgG4-AIP were collected and retrospectively analyzed.The results demonstrated that there is a variety of enhanced performance on CEUS in patients with IgG4-AIP in the early stage,for some them,especially for those with mass-type pancreatitis,their sonographic appearance and the CEUS characteristics are similar when compared with the patients with pancreatic carcinoma,with varying degrees of low enhancement in the arterial phase,venous phase and delayed stage.Therefore,it is not advisable to make a differential diagnosis based on CEUS alone,and comprehensive evaluation is warranted.
