Inflammatory pseudotumor of the liver is a rare benign mass that is often misdiagnosed as hepatocellular carcinoma at preoperative imaging. We report a case of inflammatory pseudotumor of the liver with special emphasis on the appearance at MRI after administration of mangafodipir trisodium. On T1-weighted images the lesion was slightly hypointense relative to the liver, and on T2-weighted images it was isointense with a hyperintense capsule. No tumor enhancement was seen on T1-weighted images after administration of mangafodipir trisodium. MRI with mangafodipir trisodium might help to distinguish inflammatory pseudotumor of the liver from hepatocellular carcinoma.
肝脏炎性假瘤是一种罕见的良性肿块，在术前影像学检查中常被误诊为肝细胞癌。我们报告一例肝脏炎性假瘤病例，特别强调注射锰福地匹三钠后的MRI表现。在T1加权图像上，病变相对于肝脏呈轻度低信号，在T2加权图像上，病变与高信号包膜呈等信号。注射锰福地匹三钠后，T1加权图像上未见肿瘤强化。锰福地匹三钠增强MRI可能有助于鉴别肝脏炎性假瘤与肝细胞癌。
