摘　　要：目的探讨胰腺实性假乳头状瘤(SPTP)的超声表现特征,了解其病理特征,提高超声对该病的诊断准确率。方法回顾性分析经手术病理证实的11例SPTP患者的超声检查资料,观察肿瘤位置、囊实性成分、边缘、形态、直径、主胰管扩张、包膜及钙化等情况,并分析其相应的病理特征。结果 11例SPTP患者肿瘤直径1.2~12.0 cm;肿瘤位于胰腺体尾部6例,胰头2例,胰体2例,胰颈1例。6例呈囊实性混合回声,含纤维包膜,与周围正常胰腺边界清楚;5例呈实性低回声,无包膜。4例显示钙化,4例肿瘤内部可探及血流信号。病理特征显示在纤维血管中心周围的细胞中散布着不同比例的假乳头状肿瘤细胞。结论 SPTP的超声表现有一定特征性,可反映其病理特征;临床医师应进一步提高对该病的认知程度,以提高超声对SPTP的诊断准确率。Objective To explore the ultrasonic imaging features of solid pseudopapillary tumor of the pancreas(SPTP),and to get the pathological characteristics to improve the ultrasonic diagnostic accuracy.Methods The ultrasonographic data of 11 patients with SPTP confirmed by surgical pathology were retrospectively analyzed.Preoperative ultrasonographic images were reviewed for location,existence of solid and cystic components,margin,shape,diameter,dilatation of the pancreatic duct,presence of capsule and calcification.The relative pathological characteristics of SPTP was analyzed.Results Tumor sizes ranged from 1.2 cm to 12.0 cm.The tumors were located in body and tail of pancreas in 6 cases,the head in 2 cases,the body of pancreas in 2 cases,and neck of pancreas in 1 case.6 cases had mixed solid components and cystic areas and were separated from surrounding pancreatic tissue by a fibrous capsule.5 cases were purely solid hypoecho and nonencapsulated.Varied patterns of calcification were found in 4 cases.Blood flow signals were detected in 4 cases.Pathological characteristics showed that different proportions of pseudopapillary tumor cells were distributed in cells around the center of fibrous vessels.Conclusion The ultrasonic features of SPTP have certain characteristics,which can reflect its pathological characteristics.Clinical doctor should improve the knowledge about SPTP,and to improve its ultrasonic diagnostic accuracy.
