【摘要】：目的 探讨自身免疫性胰腺炎(AIP)胰管病变的MRCP特征。方法 回顾性分析15例AIP患者的临床及MRCP影像资料,对其胰管病变进行定性及定量分析。结果 MRCP上15例AIP患者的胰管均见狭窄(15/15,100%),表现为局部胰管不可见。9例(9/15,60.00%)同时累及腹胰管和背胰管,仅腹胰管或背胰管受累各3例(3/15,20.00%)。11例(11/15,73.33%)胰管呈单发节段性狭窄,狭窄长度2.07~4.69cm(中位数3.24cm),上游胰管管径0.14~0.31cm(中位数0.19cm);4例(4/15,26.67%)胰管呈多发节段性狭窄,狭窄长度0.19~3.45cm(中位数0.82cm),狭窄段间及上游胰管管径0.14~0.70cm(中位数0.21cm)。轴位T1WI、T2WI上,13例(13/15,86.67%)胰腺弥漫性肿大,病变胰腺T1WI呈等、低信号,T2WI稍高信号为主混杂信号;2例(2/15,13.33%)胰腺局限性肿大/肿块,其胰管狭窄部位与胰腺实质病变范围一致。1例(1/15,6.67%)胰尾周围见假性囊肿。结论 AIP胰管病变的MRCP表现可分为单节段狭窄型和多节段狭窄型,大多数的非狭窄段胰管不扩张,但胰管扩张不能排除AIP。
[Abstract]:Objective to investigate the MRCP features of (AIP) pancreatic duct lesions in autoimmune pancreatitis. Methods the clinical and MRCP imaging data of 15 patients with AIP were analyzed retrospectively and the pancreatic duct lesions were analyzed qualitatively and quantitatively. Results the pancreatic duct stenosis was found in 15 cases of AIP on MRCP (15 / 15100%), 9 cases (9 / 1560.00%) were not seen in the pancreatic duct, only 3 cases (315 / 20. 00%) and 11 cases (11 / 15 73.33%) had unilateral segmental stenosis of the pancreatic duct. There were 4 cases (4 / 1526.67%) with multiple segmental stenosis in 0.14~0.31cm (median 0.19cm), 0.19~3.45cm (median 0.82cm), 0.14~0.70cm (median 0.21cm) between stenosed segments and upstream pancreatic ducts. 13 cases (13 / 1586.67%) had diffuse enlargement of pancreas on T _ 1WI (13 / 1586.67%), pancreatic T1WI was isotropic, and low signal intensity T _ 2WI mainly showed mixed signal in 2 cases (2 / 15 ~ 13.33%). The location of pancreatic duct stenosis was consistent with that of pancreatic parenchyma in 1 case (1 / 15 6. 67%) with pseudocyst around the pancreatic tail. Conclusion the MRCP findings of AIP pancreatic duct lesions can be divided into single segment stenosis type and multiple segment stenosis type. Most of the non-stenosis pancreatic duct do not dilate, but the pancreatic duct dilatation can not rule out AIP.
