摘　　要：目的 肝脏炎性假瘤(HIPT)属于一种良性局灶性炎性病变,缺乏典型的症状、体征及特异度的检查手段,容易与肝脏恶性肿瘤混淆。本研究旨在回顾性分析HIPT的超声造影特征,探讨超声造影对HIPT的诊断价值。方法 回顾性收集就诊且病理确诊的HIPT超声造影资料,分析HIPT的回声、形态、边界、超声造影动脉期、门脉期,以及延迟期增强程度及模式、增强形态等特征。结果 共纳入患者15例,男性8例,女性7例,年龄29~74岁,病灶直径0.9~8.5 cm。超声造影显示80.0%(12/15)的病灶表现为动脉期高增强、门脉期及延迟期低增强的“快进快出”模式。增强形态方面,80.0%(12/15)病灶呈整体或周边增强、内部无坏死液化区,其中呈整体高增强、内部无坏死液化区60.0%(9/15)。仅20.0%(3/15)病灶内可见坏死液化区。13.3%(2/15)病灶周边肝实质动脉期早期略呈节段性一过性高增强。结论 HIPT增强模式多为“快进快出”,动脉期增强形态以整体均匀或不均匀高增强、内部无坏死液化区为主。Objective Hepatic inflammatory pseudotumor(HIPT)was a benign lesion that lacks typical symptoms,signs or specific diagnostic examination methods and was easily confused with malignant tumors of the liver.Contrast-enhanced ultrasound(CEUS)was widely used in the diagnosis and differential diagnosis of focal liver lesions.The purpose of this study was to retrospectively analyze the characteristics of CEUS in HIPT,and to explore the diagnostic value of CEUS in HIPT.Methods The clinical and CEUS imaging data of pathologically diagnosed HIPT were collected and analyzed,including lesion echogenicity,margin,shape,and enhancement characteristics of HIPT.Results A total of 15 patients were included,aged from 29 to 74 years old,including 8 males and 7 females.with the lesion diameter ranging from 0.9 cm to 8.5 cm.Hyper-enhancement in the arterial phase and hypo-enhancement in the portal and delayed phases was found in 80.0%(12/15)of the cases.For the arterial phase enhancement morphology.80.0%(12/15)cases demonstrated global or peripheral enhancement without necrosis.The liquefaction necrosis rate of HIPT was 20.0%.Transient segmental hyper-enhancement in arterial phase was found in 13.3%(2/15)of the cases.Conclusions The enhancement pattern of HIPT is mostly"fast in and fast out",and the lesions are mainly characterized by global enhancement without necrosis for the arterial phase enhancement morphology.
