64层螺旋CT对胰腺实性假乳头状瘤的诊断价值

摘要

目的:探讨64层螺旋CT对胰腺实性假乳头状瘤(SPTP)的诊断价值,提高对该病的认识.方法:回顾性分析9例经病理证实的SPTP的CT平扫、3期增强扫描及MPR或MIP表现.结果:9例均为女性、单发,边界清楚.5例位于胰头部,2例位于胰体部,2例位于胰尾部.7例呈类圆形,2例呈分叶状.9例均表现为囊实性肿块,1例伴有钙化.3期增强扫描,肿瘤实性成分及包膜呈渐进性强化,囊性部分无强化.结论:64层螺旋CT能准确地反映SPTP影像学特点,具有重要的诊断价值.%Objective: To study the value of the 64-slice CT for Solid-pseudopapillary tumor of pancreas (SPTP)and improve the diagnosis of SPTP. Methods:CT scan, three-phase enhanced scanning performance and MPR or MIP post-processing technology of 9 cases of SPTP proved by pathology were reviewed. Results :9 cases were women ,single tumor and had clear boundaries. 5 cases were in the head or neck of pancreas ,2 cases were in the body of pancreas ,2 cases were in the tail of pancreas ,7 cases were round or oval in shape ,2 cases showed signs of lobulation. 9 cases showed cystic and solid ,1 case had calcified tissues. In three-phase enhanceed scanning , the solid ingredients and envelope were enhanced by filling progressively except cystic part. Conclusion:the 64-slice CT can reflect the SPTP imaging characteristics and it has important diagnostic value.
