一名50岁男性B型肝炎患者因肝内小结节被转诊。磁共振图像强烈怀疑是良性的。病变，如炎性假瘤，而其他放射学研究是模棱两可的。此外，扩散放大加权成像的高强度图像和低B值强烈提示良性肿瘤。尽管没有典型的临床或放射学表现，针吸活检显示肝内胆管细胞癌（ICC）。外周ICC富含纤维组织的诊断似乎需要针吸活检进行免疫组织化学染色的病理检查，因为它经常模仿其他疾病，包括良性肿瘤。
A 50-year-old male with hepatitis B was referred for a small intrahepatic nodule. Magnetic resonance images raised strong suspicion of a benign. lesion, such as an inflammatory pseudotumor, while the other radiological studies were equivocal. Furthermore, the high-intensity image on diffusion magnified-weighted imaging with a low B value strongly suggested a benign tumor. In spite of the absence of typical clinical or radiological findings, needle biopsy revealed an intrahepatic cholangiocarcinoma (ICC). The diagnosis of peripheral ICC rich in fibrous tissue seems to require needle biopsy for pathological examination with immunohistochemical staining because it frequently mimics other diseases, including benign tumors.
