摘要
目的探讨迟发性胰性脑病的MRI表现,以提高其诊断水平。方法收集我院临床确诊的7例迟发性胰性脑病的MRI资料,并进行回顾性分析。结果7例患者病灶位于脑干及丘脑(7/7),第三脑室旁、四叠体、乳头体及穹窿(6/7),小脑蚓部(2/7)及黑质(1/7);其中有3例患者累及额叶及中央前、后回皮层区;上述病变呈稍长T1长T2信号,液体衰减反转恢复序列(FLAIR)及扩散加权成像(DWI)为高信号。结论迟发性胰性脑病具有较典型的MRI表现及特定的发病部位,对临床进行早期诊断和治疗有重要意义。
Objective To study the MRI findings of delayed pancreatic encephalopathy to improve its diagnosis. Methods MRI data of 7 cases of delayed pancreatic eneephalopathy confirmed in our hospital were analyzed retrospectively. Results The lesions of all cases located in bilateral thalamus and brain stem （7/7）, around the third cerebral ventricle, gnadrigeminal bodies, mammillary body and fomix （6/7）, in vermiform lobe （2/7） and substantia nigra （1/7）. Furthermore, lesions of 31 cases involved in lobus frontalis, gyrus precentralis and posteentralis. These lesions showed slightly long T1 and long T2 signal intensity, and hyperintensity on fluid attenuated inversion recovery （FLAIR） and diffusion-weighted imaging （DWI）. Conclusion Delayed pancreatic encephalopathy presents definite MRI findings and specific localization, which is of importance for early diagnosis and treatment.
