| 目的 探讨肝脓肿的超声造影特点。方法 对16例16个穿刺病理或抗感染治疗随访证实的肝脓肿进行超声造影,并分析其造影表现与特征。结果 16个肝脓肿常规超声表现:中高回声伴低回声晕环1例(1/16, 6.3%)、不均匀中高回声7例(7/16,43.7%)、低回声伴高回声晕环7例(7/16,43.7%)、边界不清低回声1例(1/16, 6.3%);超声造影表现为病灶周边肝实质轻度增强者1例(1/16, 6.3%),病灶呈蜂窝状增强、内见多个无增强区者7例(7/16,43.7%),脓肿壁增强、但内部无增强者7例(7/16,43.7%),病灶轻度增强者1例(1/16, 6.3%)。2个病灶(2/16,12.5%)动脉期显示出肝段一过性增强征象。超声造影前16个病灶常规超声诊断正确者11个,4个病灶未能确定,1个病灶误诊;超声造影后16个病灶15个诊断正确,1个病灶误诊。结论 肝脓肿超声造影特点具有多样性,超声造影对于常规超声不能确诊的肝脓肿诊断有一定帮助。 |

| Objective To investigate the contrast-enhanced sonographic features of liver abscess. Methods Grayscale and contrast-enhanced sonographic features of sixteen liver abscesses which confirmed by pathology and follow up were analyzed. Results One (1/16, 6.3%) abscess showed as hyperechoic lesion with hypoechoic halo; seven (7/16, 43.7%) abscesses showed as inhomogeneous echogenic mass; seven (7/16, 43.7%) abscesses showed as hyperechoic mass with hyperechoic halo; one (1/16, 6.3%) abscess showed as hypoechoic mass with unclear margin. On contrast-enhanced ultrasound, one (1/16, 6.3%) abscess was equally enhanced with surrounding liver parenchyma; seven (7/16, 43.7%) abscesses showed as honeycomb-like enhancement with some small unenhanced cavities inside, seven (7/16, 43.7%) abscesses show as rim enhancement with unenhanced content; one (1/16, 6.3%) abscess was slightly enhanced. Transient arterial phase hypervascularity around the abscess was observed in 2 patients. By the aid of contrast, four nondiagnostic patients are diagnosed correctly; both grayscale and contrast-enhanced ultrasound had one misdiagnosed patient respectively. Conclusion grayscale and contrast-enhanced ultrasound features are variable and contrast-enhanced ultrasound is helpful in the diagnosis of the liver abscess. |
