目的 探讨自身免疫性胰腺炎(autoimmune pancreatitis,AIP)的经腹超声表现.方法 应用亚洲标准诊断AIP 16例,回顾性分析16例患者的经腹超声表现,对AIP的超声表现进行分型.结果 依据病变累及胰腺的范围将AIP的超声表现分为3种类型:弥漫型、节段型及局灶型,16例患者中8例表现为弥漫型(2例治疗前表现为弥漫型,治疗后1例表现为节段型,1例表现为局灶型),6例表现为节段型(包括治疗前表现为弥漫型的1例),4例表现为局灶型(包括治疗前表现为弥漫型的1例),6例回声较均匀,13例被膜增粗、增强、不光滑,3例病变内出现结节样改变,16例均无钙化,仅3例出现囊性变.结论 AIP的超声表现分为弥漫型、节段型及局灶型3种,经腹超声对其与胰腺肿瘤、普通胰腺炎有一定的鉴别诊断价值.%Objective To discuss the transabdominal ultrasound in diagnosing autoimmune pancreatitis (AIP). Methods Sixteen patients of AIP had been examined by transabdominal ultrasound in the study. Diagnosis standard is according to Asian criteria. Ultrasonic manifestations were observed. Results According to the involved sites of pancreas, AIPs were divided into 3 types: diffuse, segmental, and focal type, respectively including 6, 5 and 3 patients. Meanwhile, before and after hormone therapy, one was transformed from diffuse into focal type, and another from diffuse into segmental type. Involved pancreas was homogeneous in 6 cases, capsule became thick, enhanced and coarse in 13 cases, nodule-like echo appeared in 3 cases. No calcification was found in the whole 16 cases and cystis was found only in 3 cases. Conclusions AIP can be divided into 3 types. In most AIPs capsule becomes enhanced and coarse, some are homogenous in parenchyma. In some patients, nodule-like echo appears. Calcification and cystis are seldom found. These are probably helpful to distinguish AIP from pancreatic tumor and common pancreatitis.
