Focal nodular hyperplasia (FNH) commonly occurs in women; it is usually asymptomatic and sometimes difficult to differentiate from hepatocellular carcinoma (HCC).
A large space-occupying lesion in the right lobe of the liver was incidentally detected in an adult man and diagnosed as HCC. Transcatheter arterial chemoembolization was applied once monthly for 2 years, but the lesion did not decrease in size. It was revealed by biopsy to be FNH. Eleven years later, the patient underwent liver resection due to hemorrhage and the pathological examination confirmed FNH.
For a space-occupying lesion, it is prerequisite to pathologically confirm the diagnosis and the corresponding intervention can be effective.
局灶性结节性增生（FNH）常见于女性；通常无症状，有时难以与肝细胞癌（HCC）鉴别。
一名成年男性偶然发现肝脏右叶有一个大的占位性病变，诊断为HCC。每月进行一次经动脉化疗栓塞，持续2年，但病变大小未减小。活检显示为FNH。11年后，患者因出血接受肝切除术，病理检查确诊为FNH。
对于占位性病变，病理确诊是前提，相应的干预才可能有效。
