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 improve the understanding of the imaging features of chronic pseudocyst pancreatitis. Materials and Methods Retrospective analysis of 12 cases of clinical and pathological diagnosis of pseudocyst pancreatitis characteristics. Results All 12 cases were found with solid mass of the pancreas, most of which were round in shape with a diameter of 2.5 ~ 4 cm. The rules of the edge were more homogeneous. If the tumor is larger, the density is not uniform, the center is necrotic, the edge is irregular. Eight cases of calcification within the tumor. CT enhanced scan mass was significantly enhanced. Eleven patients were located in the head of the pancreas and one was located in the body of the pancreas. Seven cases of B-hypoechoic, five cases of uneven echo. Conclusions Pseudoepithelial pancreatitis is extremely difficult to differentiate from pancreatic cancer, sometimes impossible. However, combined with clinical process, comprehensive analysis of image features, can improve the diagnostic rate.
