Hypointensity in the hepatocyte phase is believed to be a key feature of hypovascular early hepatocellular carcinoma, which indicates malignancy. The 3 cases we present suggest that the converse is not true. Three small hepatocellular lesions showed isointensity/hyperintensity on gadoxetic acid-enhanced, hepatocyte-phase magnetic resonance images and were pathologically confirmed as early hepatocellular carcinomas. We conclude that isointensity or hyperintensity in the hepatocyte phase does not always represent benignity of hepatocellular lesions in the cirrhotic liver.
肝细胞期低信号被认为是乏血供早期肝细胞癌的关键特征，提示恶性病变。我们所呈现的3例病例表明情况并非如此。3个小肝细胞性病变在钆塞酸增强磁共振成像的肝细胞期表现为等信号/高信号，病理证实为早期肝细胞癌。我们得出结论，在肝硬化肝脏中，肝细胞期等信号或高信号并不总是代表肝细胞性病变为良性。
