摘要
目的:探讨不典型肝脓肿的超声表现及超声诊断技术临床应用价值。方法:回顾性分析32例不典型肝脓肿的超声表现,其中3例超声造影检查。全部病例经临床随访及穿刺活检后经病理证实。结果:不典型肝脓肿随病理过程的变化超声表现各不相同,可表现为实性低回声、等回声及偏高回声,与周围肝组织分界不清,内回声强弱不等,分布极不均匀,可见形态不规则的小片状液区。部分病灶内可见正常肝内门脉血管穿行。注射对比剂后整个过程病灶内部未见增强,均呈低回声,病灶边界较造影前清晰。结论:不典型肝脓肿声像图复杂多变,超声检查仍为可靠方法,超声造影更具诊断意义。
Objective：To analyze the imaging features and evaluate the diagnostic value of ultrasonography in atypical liver abscess. Methods：32 patients with atypical liver abscess were retrospectively analyzed, 3 patients were studied with contrast-enhanced ultrasound. All cases were comfirmed by clinical follow-up aspiration biopsy. Results： The manifestation of atypical liver abscess on ultrasonography varied with the clinical course and exhibited pathologic changes, solid low echo, equal echo and high echo image with ill-defined margins, and irregular shape with inhomogeneous internal echoes uneven distribution. Contrast-enhanced ultrasound demonstrated low echo image of the lesion but the margin was better demarcated without enhancement than it. Conclusion：The ultrasonic imaging features of alypical liver abscess were intricate and variable. By careful analysis and close follow up, ultrasonography proves valuable in the diagnosis of atypical liver abscess especially with the aid of contrast study and ultrasound guided aspiration.
