摘要
目的:探讨胰腺实性假乳头状瘤(solid pseudopapillary tumor of pancreas,SPTP)的超声诊断和误诊原因.方法:分析本院2008-06/2011-06经手术、病理证实11例SPTP的超声表现和相关临床资料.结果:11例均为单发圆形或椭圆形、实性或混合性略低回声团;9例(9/11)边界较清楚,8例(8/11)包膜完整,10例(10/11)瘤后回声无衰减,9例(9/11)相邻组织器官受压、移位;8例(8/11)瘤内及周边可见少许血流信号;除1例胰头SPTP其远端胰管略宽外(0.3cm),其余所有患者胆管、胰管均无扩张.术前超声检查明确诊断5例(5/11);结合年龄、性别、CT高度可疑诊断3例(3/11);因瘤体形态、包膜欠规整,局部增厚或呈分叶状外凸生长,与周围组织界限不清,瘤内结构回声复杂、多样等因素延、误诊3例(3/11).结论:SPTP的超声表现特征为一组"声像图征象群",是超声诊断SPTP的重要线索和可靠指标.其声像图复杂、多样.医师对该疾病缺乏足够的认识是造成延、误诊断的主要原因.
AIM： To study the ultrasound diagnosis and causes of misdiagnosis of solid pseudopapillary tumor of pancreas （SPTP）. METHODS： Ultrasonic and clinical data for 11 patients with pathologically confirmed SPTP who underwent surgical treatment from June 2008 to June 2011 at our hospital were analyzed retrospectively.RESULTS： All cases had a single round or ovalshaped, mixed slightly low echo mass. The tumor had a clear boundary in 9 cases and a complete capsule in 8 cases. Ten cases had no posttumor echo attenuation. Adjacent tissue or organ compression and displacement were observed in 9 cases. Eight cases showed little blood flow in and around the tumor. All cases showed no dilatation in the pancreatic duct and bile duct, except for 1 case showing slight widening of distal pancreatic duct. Five cases of SPTP were diagnosed by ultrasound before operation; three cases were highly suspected to have SPTP after fully considering the age, sex, and CT findings. Because of irregular tumor morphology and capsule, local thickening or lobulated convex growth, unclear surrounding tissue, complicated structure and echo of internal tumor, three cases were misdiagnosed. CONCLUSION： SPTP display a group of ＂sonographic signs＂, which are important clues to and basis for the diagnosis of SPTP. Main reasons for misdiagnosis are complicated and diverse.
