胰腺实性假乳头状瘤的CT、MRI诊断

目的探讨胰腺实性假乳头状瘤的CT、MRI表现,提高对该病的诊断水平。方法3例经手术病理证实的胰腺实性假乳头状瘤术前均进行CT平扫及增强检查,其中1例还进行MRI平扫及增强检查。回顾分析其CT、MRI表现并复习相关文献。结果CT均表现为囊实性肿块,1例位于胰头部,2例位于胰体尾部,胰胆管未见明显扩张;MRI上T1WI表现为稍低信号,T2WI以稍高信号为主,病灶前缘可见小片高信号。增强后实质部分及囊壁强化。结论胰腺实性假乳头状瘤的CT、MRI表现具有一定的特征性,综合分析可以获得诊断。

CT and MRI diagnosis of solid-pseudopapillary tumor of pancreas(a report of 3 cases)

Objective To study CT and MRI findings of solid-pseudopapillary tumor in pancreas and to improve the diagnosis ability of this disease.Methods CT were performed in all three patients with solid-pseudopapillery tumors of pancreas proved by surgery and pathology.Of three patients,plain and enhanced MRI was performed in one patient.CT and MRI findings were analyzed retrospectively with a review on relative literatures.Results The main symptom was bellyache,and no jaundice.All patients were found to have solid-cystic mass in pancreas,one in the head and the other two in the body and tail respectively.MRI findings in one patient demonstrated mild low signal on T1WI,mainly mild high signal on T2WI,and a piece of high signal in the front of the focus.On enhanced CT and MRI,the wall of cyst and solid portions of the mass showed enhancement.Conclusion CT and MRI findings of solid-pseudopapillery tumor of pancreas show some characteristics,and this disease can be diagnosed by compositive analysis.
