摘要 目的 探讨常规超声与胰腺神经内分泌肿瘤(pNETs)病理分级的相关性及其超声造影(CEUS)表现。方法 回顾性分析44例经手术或穿刺后病理证实的pNETs的术前常规超声图像及造影表现。结果 常规超声检出41例pNETs,病灶较多发生于胰头部(17/41,41.46%)及胰尾部(14/41,34.14%),不同病例分级pNETs病灶在发生部位、病灶直径大小无统计学差异。常规超声上,不同病理分级pNETs病灶在边界、形态、是否引起胰胆管扩张及是否发生转移四个方面的差异具有统计学意义。转移性pNETs与非转移性pNETs病灶仅在边界方面差异具有统计学意义。另外,12例pNETs病灶在CEUS以动脉期呈高增强或等增强为主要特征,静脉期可出现高增强、等增强或低增强,但不同病理分级的pNETs增强模式并无统计学差异。结论 常规超声的不同表现与pNETs的病理分级具有一定相关性,提高了超声术前定性诊断效能,且对于预测pNETs是否发生转移具有一定的价值。CEUS时pNETs以动脉期呈高增强或等增强为主要特征。
