To assess the images of inflammatory pseudotumor of the liver (IPL) on all phases of contrast-en-hanced ultrasonography (CEUS) in patients with fatty liver.MethodsThe features of IPL on two-dimensional ultrasound,Doppler and CEUS in 31 fatty liver patients were analyzed.ResultsIn 71% cases,there were 2 or 3 adjacent nodes in lesions,which were closed to each other and looked like "dumbbell" or "sub-section". In 77.4% cases, the distance from lesions to the liver capsule was less than 3cm. There were punctuate echogenic in 35.5% nodes. In 67.7% cases,the liver tissue surrounding lesions were slightly enhanced in the early arterial phase. In 54.8% cases, that were slightly enhanced in arterial and portal phases, and there were line-like and membrane-like extension to the central zone of lesions. In 90.3% cases, the whole lesions were not enhanced or the central zone appeared irregular non-enhanced echo area in all phases.ConclusionCEUS is an im-portant imaging method for diagnosis and differential diagnosis of the hypoechoic lesions in fatty liver, and it is definitely useful in clinical application.%目的 探讨脂肪肝背景下肝脏炎性假瘤(IPL)超声增强造影各时相的特点及与其它相似二维图像病变的鉴别要点.方法 选取伴有脂肪肝的31 例IPL 患者,对其IPL 病灶的二维、彩色多普勒及增强造影的超声检查表现进行总结分析.结果 71.0%的病灶相邻出现2～3 个结节,相互紧贴呈哑铃状或分节状改变.77.4%的病灶位于距肝包膜3cm以内,35.5%的结节内出现点状强回声.67.7%超声增强造影病灶周边肝脏组织在动脉早期轻微增强,54.8%的病灶周边肝脏组织动脉期、门脉期轻度增强,并见线样、隔膜样向病灶中间延伸.90.3%的病灶整体无增强或近中间部分在各时相出现不规则无增强回声区.结论 脂肪肝背景下低回声病灶(IPL 及其他病变)行超声增强造影,是进行定性诊断与鉴别诊断的重要影像学方法,具有明确的临床应用价值.
