| 目的：总结肝脏局灶性结节增生(FNH)的典型与非典型超声造影表现,探讨超声造影（CEUS）在肝脏常见的良性病变中的诊断价值。
材料与方法：2014年6月-2016年3月对205例肝脏局灶性病变的307个病灶行超声造影检查，以病理诊断为金标准，评价CEUS诊断FNH的诊断效能，并着重总结不典型FNH病例CEUS增强特征。
结果： 205例307个病灶中共161例213个病灶获得病理诊断，其中31例确诊为FNH共34个病灶，CEUS诊断FNH的敏感性、特异性、阳性预测值、阴性预测值及准确率分别为91.2%（31/34）、97.8%(175/179)、88.6%（31/35）、98.3%（175/178）及96.7%(206/213)。其中3个FNH病灶造影表现为动脉期呈高或等增强，门脉期或延迟期减退为低增强的恶性病灶不典型增强特点。
结论：CEUS对FNH的诊断具有较高的价值，对少数不典型增强病灶的诊断, 需结合肝炎背景、AFP及其它影像学资料，必要时应行超声引导穿刺活检或手术切除明确组织病理学诊断。 |

| Abstract: |
| 【Abstract】 To summarize the hepatic focal nodular hyperplasia(FNH)of the typical and atypical performance of CEUS, and to evaluate the diagnostic value of CEUS in common benign focal hepatic lesions. .Methods: CEUS was performed on 307 lesions of 205 focal liver lesion cases During June 2014 and March 2016, and the pathological diagnosis were the gold standard, the diagnostic performance of CEUS was evaluated, with emphasis on the enhanced features of CEUS in atypical cases. Results: 161 cases with a total lesion number of 213 were confirm in the 205 cases. Among those, 31 cases with 34 lesions were diagnosed as FNH. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of diagnosing of FNH using CEUS were 91.2% (31/34), 97.8% (175/179), 88.6% (31/35), 98.3% (175/178) and 96.7% (206/213). Three lesions showed malignant enhancement feature that is hyperenhancement during the arterial phase followed by wash out during the portal venous and late phasesS. |
