Objective:To study the pathological morphology and immunohistochemical features of hepatic focal nodular hyperplasia (FNH).Methods:Sixteen cases of FNH were studied with HE staining and immunohistochemistry.Results:The pathological features were a solitary and nodular mass with central fibrous scar that contained thick-walled vessels and proliferated bile ducts.Internodular bile ducts proliferation is abundant and merge imperceptibly with hepatocytes near the fibrous septa. Immunohistochemically,...

Objective:To study the pathological morphology and immunohistochemical features of hepatic focal nodular hyperplasia (FNH).Methods:Sixteen cases of FNH were studied with HE staining and immunohistochemistry.Results:The pathological features were a solitary and nodular mass with central fibrous scar that contained thick-walled vessels and proliferated bile ducts.Internodular bile ducts proliferation is abundant and merge imperceptibly with hepatocytes near the fibrous septa. Immunohistochemically, the Keratin expressed by hepatocytes and by the proliferated bile ducts were similar.Conclusion: FNH is a tumor-like lesion , in which the proliferated bile ducts probably arised from hepatocellular metaplasia in the nodules.It should be differentiated from hepatocellular hepatocellular adenoma,(fibrolamellar hepatocellular carcinoma in particular)and nodular regenerative hyperplasia of the liver.

目的 :探讨肝局灶结节性增生 (FNH)的病理形态及免疫组化特征。方法 :采用 HE和免疫组化染色对 16例肝 FNH进行病理学观察。结果 :FNH病理特征为孤立的、中央有纤维瘢痕的结节性肿块 ,纤维瘢痕中可见厚壁血管及增生的小胆管。结节间增生的小胆管与结节周边肝细胞相移行 ,且两者角蛋白表达相似。结论 :FNH是一瘤样病变 ,其中增生的小胆管可能来自结节内肝细胞化生 ,应与肝细胞腺瘤、肝细胞肝癌 (尤其纤维板层型肝癌 )及结节状再生性增生进行鉴别。

Objective:To improve diagnostic accuracy of hepatic focal nodular hyperplasia(FNH)by studying MRI multiphase scanning.Methods:A retrospective analysis was made on the unenhanced and dynamic enhanced MR images of 15 patients(totally 16 lesions)with surgical and pathological proved FNH.Results:MR images of 16 lesions always showed appearance with slightly low or isointense on T1-weighted images and isointense or slightly hyperintense on T2-weighted images.All lesions had apparent enhancement in the arterial...

Objective:To improve diagnostic accuracy of hepatic focal nodular hyperplasia(FNH)by studying MRI multiphase scanning.Methods:A retrospective analysis was made on the unenhanced and dynamic enhanced MR images of 15 patients(totally 16 lesions)with surgical and pathological proved FNH.Results:MR images of 16 lesions always showed appearance with slightly low or isointense on T1-weighted images and isointense or slightly hyperintense on T2-weighted images.All lesions had apparent enhancement in the arterial phase and prolonged enhancement in the portal venous phase and delayed phase.Central scar was found in 5 FNH lesions on unenhanced images and in 11 FNH lesions on dynamic contrast-enhanced images,and demonstrated late enhancement.Conclusion:The unenhanced and dynamic contrast-enhanced MRI scanning can fully show the pathologic and the blood supplying characteristics of FNH and improve differentiating ability from other malignant hypervascular tumors.

目的:分析肝脏局灶性结节增生(FNH)的平扫和动态增强的MRI表现及诊断价值,提高FNH诊断的准确率。方法:回顾性分析15例(16个病灶)经病理证实的FNH的平扫及动态增强MRI表现。结果:16个病灶于T1WI呈略低信号或等信号,T2WI呈略高信号或等信号。增强扫描动脉期呈明显强化,在门脉期及延迟期呈等或略高强化。5个病灶在平扫MRI上显示中央瘢痕,11个病灶在动态增强MRI上显示中央瘢痕,均见延迟强化。结论:平扫和动态增强MRI检查能较全面显示FNH的病理特征和血供特点,明显地提高与其他富血管恶性肿瘤的鉴别诊断能力。
