目的 :探讨不典型小胰头癌的CT间接征象的鉴别诊断。材料与方法 :10例病例均先行CT平扫 ,再做CT动态增强扫描。其中 4例小胰头癌及 3例胆总管下段结石患者均已经手术病理证实 ,另 3例胆总管下段炎症患者经抗炎治疗痊愈出院。结果 :4例小胰头癌患者上中段总管及肝总管、胆囊管、肝内胆管明显扩张 ,胆囊明显扩大 ,并有主胰管扩张 ,胰周间隙欠清晰。 6例胆总管下段炎性狭窄与结石患者胆道系统扩张不如前者明显 ,且上中段胆总管扩张由上至下呈逐渐缩小型。结论 :不典型小胰头癌的CT间接征象在下段胆总管炎性狭窄、结石的鉴别诊断中具有重要作用
Objective: To explore the differential diagnosis of atypical small pancreatic cancer with indirect signs of CT. Materials and Methods: CT scan was performed in all 10 cases before CT dynamic contrast-enhanced scanning. 4 cases of pancreatic head cancer and 3 cases of lower common bile duct stones have been confirmed by surgical pathology, and the other 3 cases of common bile duct inflammation in patients with anti-inflammatory cured and discharged. Results: The upper and middle common hepatic duct, cystic duct and intrahepatic bile duct of 4 patients with small pancreatic head cancer were obviously expanded, the gallbladder was obviously enlarged, the main pancreatic ducts were dilated, and the peripancreatic space was not clear. Six cases of biliary duct inflammation and stenosis of lower biliary duct stones in patients with less obvious than the former, and the upper middle section of the common bile duct dilatation from the top was tapering. Conclusion: The indirect signs of CT in atypical small pancreatic head cancer play an important role in the differential diagnosis of common bile duct inflammation and calculi
