摘　　要：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。Objective: To study the differential diagnosis of the indirect CT signs of the atypical small carcinoma of caput pancreas (ASCCP). Methods: All of the 10 patients, ASCCP ( n =4), the stone ( n =3) and the inflammation ( n =3) of the inferior part of ductus choledochus received enhanced CT scan. Results: Dilation of the superior and middle part of ductus choledochus, ductus hepaticus common, ductus cysticus, ductus hepaticus and vesica fellea and ductus pancreas was observed in all of the 10 cases. The degree of the dilation in ASCCP was more obvious than in the stone or the inflammation of the inferior part of ductus choledochus. Conclusions: The indirect CT signs of ASCCP are very important to differentiate from the inflammatory stenosis or stone of the inferior part of ductus choledochus.
