摘要
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71O％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。
Objective To assess the images of inflammatory pseudotumor of the liver （IPL） on all phases of contrast-enhanced ultrasonography （CEUS） in patients with fatty liver. Methods The features of IPL on two-dimensional ultrasound, Doppler and CEUS in 31 fatty liver patients were analyzed. Results In 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. Conclusion CEUS 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.
