背景与目的:超声是体检发现胰腺实性假乳头状瘤(solid pseudopapillary tumor of the pancreas,SPTP)的重要手段,本研究对SPTP的超声表现及其诊断价值进行探讨。方法:收集复旦大学附属肿瘤医院经手术病理证实的62例SPTP的超声检查资料,并进行总结分析。结果:本组中5例患者超声检查漏诊。SPTP的超声声像学特征包括:肿瘤多较大,以胰体尾多见,边界可较为清楚,形态较为规则,多呈低回声,或者为低回声伴无回声,内部回声多不均匀,少数患者可有钙化,病灶内多无明显血流,多无主胰管及胆总管扩张,多无区域淋巴结肿大。结论:SPTP的超声表现有一定特征性,具有重要的临床应用价值。
BACKGROUND & OBJECTIVE: Ultrasound is an important method for the discovery of solid pseudopapillary tumor of the pancreas (SPTP) by physical examination. This study was to investigate the ultrasound manifestation and diagnostic value of SPTP. METHODS: Ultrasonographic data of 62 cases of SPTP confirmed by operation and pathology at the Cancer Hospital of Fudan University were collected and analyzed. Results: Ultrasonography was missed in 5 patients in this group. Ultrasonic acoustic features of SPTP include: Larger tumors, more common pancreatic and body tails, clearer borders, more regular morphology, mostly hypoechoic, or hypoechoic with no echo, and multiple internal echoes. The patient may have calcification, there is no obvious blood flow in the lesion, there is no expansion of the main pancreatic duct and common bile duct, and there is no regional lymph node enlargement. Conclusion: The ultrasound manifestation of SPTP has certain characteristics and has important clinical application value.
