FNH

Objective To investigate MSCT findings of hepatic focal nodular hyperplasia ( FNH ), and improve its diagnostic value.

目的提高对肝脏局灶性结节 增生 CT 表现的认识, 探讨多层螺旋CT的诊断价值.

[ Conclusion] FNH is a benign hyperplastic lesion of the liver. It should be differentiated from hepatic adenomatous hy-perplasia nodule, hepatocellular adenoma, alpha-fetoprotein negative hepatocellular carcinoma and fibrolamellar hepato-cellular carcinoma histologically.

[结论]FNH为肝脏良性增生性病变，组织学上应与肝腺瘤样增生结节、肝细胞腺瘤、AFP阴性的肝细胞肝癌和纤维板层层状肝细胞癌进行鉴别。

FNH showed enhance quickly in atrerial phase but disappeared in parenchymal phase;

肝局灶性结节增生表现为快速增强，但在实质期开始消退；

Focal nodular hyperplasia ( FNH ) of liver is a benign lesion that is often asymptomatic.

局限性结节 增生 是一良性肝脏病杜,临床上常无症状,约占原 发性 肝肿瘤的8%.

Group C included 13 focal nodular hyperplasia ( FNH).

C组：肝内局灶性结节性增生（FNH）13例。

Conclusion MR and CT especially dynamic contrast enhancement is of great value to the diagnosis of FNH.

结论MR、CT尤其是动态增强是诊断肝FNH的有效方法。

Conclusion Multiphasic contrast-enhanced CT scan is specific and accurate in diagnosing FNH and can be used to guide the clinical treatment.

结论CT多期增强扫描对肝脏局灶性结节增生的诊断具有特征性，且较准确，对临床治疗具有指导意义。
