摘要
目的对比分析经腹超声、多层螺旋CT(MSCT)在胰腺实性假乳头状瘤(SPTP)中的临床价值。方法回顾分析本院2017年1月至2019年8月收治的38例胰腺实性假乳头状瘤患者的临床及影像资料,比较不同方式对SPTP的诊断价值及图像表现。结果MSCT对SPTP诊断正确率显著高于经腹超声检查;超声中,所有病灶边缘清晰,包膜完整,其中囊实性和囊性病灶CDFI可见少许血流信号,实性病灶CDFI未见血流信号;MSCT多表现为类圆形或椭圆形病灶,部分囊性病灶边缘可见大小不一囊壁结节,实质性部分病灶在增强扫描中动脉期呈现不均匀轻度强化,门脉期和延迟期表现为渐进性的增加强化,而囊性部分病灶在增强前后均未见明显强化表现。结论超声和MSCT中均可表现SPTP的相关影像特征,但MSCT检查对SPTP的诊断正确率更高,结合临床表现及图像特征对SPTP诊断及治疗指导更具有临床价值。
Objective To compare and analyze the clinical value of transabdominal ultrasound and multi-slice spiral CT(MSCT)in solid pseudopapillary tumor of pancreas(SPTP).Methods The clinical and imaging data of 38 patients with solid pseudopapillary tumor of pancreas treated in our hospital from January 2017 to August 2019 were retrospectively analyzed,and the The value and images of different methods in diagnosis of SPTP were compared.Results The diagnostic accuracy of MSCT for SPTP was significantly higher than that of transabdominal ultrasound.In ultrasound,the edges of all lesions were clear and the capsule was intact.Among them,a little blood flow signal was seen in CDFI of cystic solid and cystic lesions.There was no blood flow signal in CDFI of solid lesions.MSCT mostly showed round or oval-shaped lesions.Some cystic lesions showed cyst wall nodules with different sizes in the edges.Some parenchymal lesions showed uneven and mild enhancement in the arterial phase during of enhancement scan and in portal phase and delayed phase showed a progressive increasing of enhancement,while some cystic lesions showed no obvious enhancement before and after enhancement.Conclusion Both ultrasound and MSCT can show the relevant imaging features of SPTP,but the MSCT examination has a higher diagnostic accuracy for SPTP.It combines clinical manifestations and image features to guide the diagnosis and treatment of SPTP,which has more clinical value.
