The purpose of this study was to describe our experience with three patients who had pathologically proven focal nodular hyperplasia (FNH)-like nodules that radiologically mimicked hepatocellular carcinoma (HCC).
FNH-like nodules may radiologically mimic HCC, appearing as hypervascular masses on contrast-enhanced CT images and as high-signal-intensity masses on superparamagnetic iron oxide-enhanced MR images. Pathologically, there is the presence of a high number of unpaired arteries and sinusoidal capillarization, which may mimic HCC. Thus, it is important to differentiate FNH-like nodules radiologically, pathologically, and clinically from HCC.
本研究的目的是描述我们对三名患者的经验，这些患者经病理证实为局灶性结节性增生（FNH）样结节，其在放射学上模仿肝细胞癌（HCC）。
FNH样结节在放射学上可能模仿HCC，在对比增强CT图像上表现为高血供肿块，在超顺磁性氧化铁增强磁共振图像上表现为高信号强度肿块。在病理上，存在大量不成对动脉和窦状毛细血管化，这可能模仿HCC。因此，从放射学、病理学和临床上将FNH样结节与HCC区分开来很重要。
