摘　　要：目的探讨肝血管瘤超声造影不典型增强模式,评价超声造影对肝血管瘤的诊断价值。方法回顾性分析我科2011年1月至2013年6月行超声造影检查,且造影不能确诊或误诊的21例肝血管瘤的超声造影表现。全部病例经增强CT、磁共振成像(MRI)等确诊。结果 15例病灶延迟期表现为低增强,6例病灶门脉期表现为低增强。结论对于门脉期、延迟期有消退的病灶需结合增强CT、MRI等其他检查以除外恶性病变。Objective To discuss the atypical enhancement pattern of liver hemangioma and evaluate the diagnostic value of contrast-enhanced ultrasound（CEUS）on that.Methods To review and analyze the dynamic images in 21 cases undiagnosed or misdiagnosed on contrast ultrasonography.The final diagnosis was confirmed by contrast-enhanced CT or MRI.Results Fifteen cases show the hypo-enhanced lesions in the late phase.Six cases show the hypo-enhanced lesions in the portal phase.Conclusion When the lesions present atypical enhancement patterns,the diagnosis is difficult and still requires further investigation using enhanced CT or MRI,especially for lesions ruled out at the portal phase or late phase.
