胰腺实性假乳头状瘤的超声表现

摘要

Background and purpose:Ultrasound is a regular screening method of solid pseudopapillary tumor of the pancreas (SPTP). This study was to summarize the diagnostic value of ultrasound to SPTP.Methods:Clinical and ultrasound data of 62 SPTP cases in Fudan University Shanghai Cancer Center were retrospectively collected and analyzed.Results:Five cases of SPTP were undetected by ultrasound in the group. The features of ultrasound including: large mass located at the body and tail of the pancreas, clear boundary and regular shape, low ultrasound with uneven signal, or low signal mixed with no signal. A few cases have calciifcation and blood signal. Most of the cases presented no dilation of main pancreatic duct and bile duct and regional lymph nodes enlargement. Conclusion:Ultrasound can be used to detect SPTP which has special ultrasound signal features.%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。
