摘要
目的 提高对慢性假肿瘤性胰腺炎的影像学特征的认识。材料与方法 回顾性分析 12例经临床、病理诊断的假肿瘤性胰腺炎的特点。结果 12例均见胰腺实质肿块形成 ,大多为类圆形 ,直径为 2 .5～ 4cm ,边缘规则 ,肿块较均质。如肿块较大 ,则密度不均 ,中心坏死 ,边缘不规则。 8例肿块内有钙化。CT增强扫描肿块大多呈明显强化。 11例位于胰头部 ,1例位于胰体部。 7例B超呈低回声 ,5例为不均匀回声。结论 假肿瘤性胰腺炎与胰腺癌的鉴别极为困难 ,有时甚至是不可能的。但是结合临床过程 ,影像特征综合分析 ,可提高诊断率。
Objective To make a further understanding of the imaging features of the chronic pseudotumorous pancreatitis.Materials and Methods CT findings in 12 patients with clinically- and pathologically-proved pseudotumorous pancreatitis were retrospectively analyzed.Results Mass shadow in pancreatic parenchyma was seen in all 12 patients. The masses presented as round, homogeneous density with regular edge and 2.5～4 cm in diameter. Calcification within the mass was seen in 8 cases. Bigger mass demonstrated inhomogeneous density and central necrosis with irregular edge. Marked enhancement were seen in most cases. One mass was located in the pancreatic body, while the other 11 in pancreatic head. On sonography, 7 cases demonstrated low echo and 5 cases inhomogeneous echo.Conclusion A correct diagnosis of chronic pseudotumorous pancrea- titis can be made based on analyzing clinical history and imaging features, although differentiation with pancreatic carcinoma is usually very difficult in some cases.
