【摘要】：目的:探讨沟槽区胰腺炎的MSCT征象,提高对该病的影像学诊断水平。方法:回顾性分析53例GP患者的临床及CT影像学资料,所有病例经手术病理或ERCP活检病理证实。观察沟槽区肿块或囊状病变的强化特点和分型,以及邻近结构的影像学改变。结果:53例的主要CT表现:(1)均可见沟槽区软组织增厚改变,CT平扫呈等或混杂稍低密度,动脉期呈轻度强化或无强化,实质期呈渐进性不均匀延迟强化;(2)57%(30/53)伴有副胰管开口邻近十二指肠降部肠壁或胰头实质的囊性变(长径10~48mm);(3)十二指肠降部肠壁增厚45例(85%),其中40例为弥漫性水肿,5例为局部性水肿;(4)胰管扩张占19%(10/53),胆总管扩张占15%(8/53);(5)其它:沟槽区积液占89%(47/53),淋巴结炎(短径8~17mm)占23%(12/53)。结论:沟槽区胰腺炎的MSCT征象具有一定特征性,双期增强扫描对本病的诊断具有重要价值。
[Abstract]:Objective: to investigate the MSCT features of sulcus pancreatitis and to improve the imaging diagnosis of the disease. Methods: the clinical and CT imaging data of 53 patients with GP were retrospectively analyzed. All cases were confirmed by pathology or ERCP biopsy. The enhanced features and types of sulcus masses or cystic lesions and the imaging changes of adjacent structures were observed. Results the main CT findings of 53 cases were as follows: (1) the thickening of soft tissue in the sulcus area was observed. The CT plain scan showed equal or slightly mixed density, and the arterial phase showed slight or no enhancement. (2) 57% (30 / 53) of them had cystic degeneration (long diameter 10~48mm); (3) near the descending duodenum wall or pancreatic head parenchyma (long diameter 10~48mm); (3), of which 40 cases were diffuse edema in 45 cases (85%). (4) pancreatic duct dilatation accounted for 19% (10 / 53), choledochal dilatation 15% (8 / 53); (5) others: the sulcus region effusion accounted for 89% (47 / 53), lymphadenitis (8~17mm) 23% (12 / 53). Conclusion: MSCT features of grooved pancreatitis are characteristic, and dual phase contrast enhanced scan is of great value in the diagnosis of this disease.
