【摘要】 目的 分析胰头部肿块型胰腺炎CT误诊和漏诊原因,提高对胰头部肿块型胰腺炎CT诊断和鉴别诊断能力。方法 对15例术前误诊的胰头部胰腺炎病例进行回顾性分析。CT检查采用单排或多排螺旋CT进行扫描,层厚5～8mm或2mm。结果 术前CT误诊为胰腺癌的15例胰头部胰腺炎，术后11例经手术病理证实为胰腺炎，4例为穿刺活检证实。结论 注意螺旋CT扫描方法,仔细阅片,全面分析,能减少CT对肿块型胰腺炎的误诊率和漏诊率。

    【Abstract】 Objective To improve the CT diagnosis and differential diagnosis of chronic pancreatitis with mass in the head of the pancreas by analysing the cause of CT misdiagnosis.Methods 15 patients with chronic pancreatitis with mass in the head of the pancreas misdiagnosed at pre-operation by CT was analyzed retrospectively.Spiral CT or MSCT scan were performed in pancreas phase,the slice thickness was 5～8mm or 2mm.Results In 15 cases of chronic pancreatitis with mass in the head of the pancreas: 15 cases were misdiagnosed as pancreatic carcinoma at pre-operation by CT,and in these 15 cases,11 cases were confirmed chronic pancreatitis by pathology,other 4 cases were confirmed by the biopsy of puncture.Conclusion By paying attention to the method of CT scan,and carefully analyzing the data of CT images,the misdiagnostic rate of chronic pancreatitis with mass in the head of the pancreas can be decreased. ......
