【摘要】 目的探讨超声造影对于小病灶泡型包虫病的诊断价值。方法回顾性分析我院2008年1月至2015年6月间,经术后病理证实的小灶肝泡型病的超声及超声造影表现。9例患者,共计17个病灶被纳入研究,所有病灶直径均≤3cm。患者术前均接受超声造影检查。超声造影剂采用声诺维,通过静脉推注,每次推注剂量2.4ml。回顾性分析病灶的灰阶超声以及超声造影的表现。结果灰阶超声显示12例为稍强回声结节,5例呈低回声结节伴周边低回声晕,5例中伴有钙化灶。结节回声不均匀,形态较规则。术后病理证实均为肝泡型包虫病。结论超声造影对于肝泡型包虫病有一定的诊断价值,特别是对于小病灶,表现不典型的病例。更多还原

【Abstract】 Objective:To investigate the features of small lesions of hepatic alveolar echinococcsis paragonimiasis(AE) by contrast enhanced ultrasound(CEUS).Methods:US and CEUS features of seventeen lesions histopathologically proven hepatic AE were retrospectively reviewed.Nine patients with seventeen hepatic AE lesions who were admitted to our hospital between January 2008 and June 2015 were enrolled.All hepatic AE lesions were small(≤3 cm).The US and CEUS examinations were performed with a Philips IU22 scannerwith a 1–5-MHz convex transducer.After US was completed,the CEUS study was performed.Pulse-inversion harmonic imaging was used for CEUS.A bolus injection of 2.4 m L of a sulfur-hexafluoride-filledmicrobubble contrast agent(Sono Vue) was administered.The features of the lesions by US and CEUS were retrospectively reviewed.Results:The mean size of the lesions was 1.8 ± 0.7 cm(range:1.0–3.0 cm).Five patients had a lesion in the right hepatic lobe;two had two lesions in the left hepatic lobe;and two patients had four lesions in the right lobe.Five lesions were hypoechoic nodules and twelve were hyperechoic nodules.Four lesions with hypoechoic nodule had small dotted calcifications.Four nodules showed short striated blood-flow signals in the lesions.By CEUS,All the lesions were hypoechoic with mixed content.All lesions were rim enhanced with irregular piece-like nonenhanced internal areas and showed nonhomo-geneous hypo-enhancement during the arterial phase,with mixed echogenicity.更多还原
