| 摘 要： | 肝脏局灶性结节增生(FNH)不是真正的肿瘤。病理学上FNH是正常的肝细胞对先天性或获得性异常血管的反应性增生．病变中主要包括异常血管、正常的肝细胞、Knffer细胞、胆管及增生的纤维结缔组织。CT检查中典型表现为动脉及门静脉早期明显均匀增强的多血管性肿块．并且病变中心出现延迟强化的中心瘢痕。典型的MRI表现包括等或略长T1及等或略长T2信号．中心瘢痕呈明显的长Tl长T2信号．SPIO增强有助于病变的诊断。

| Abstract: | Focal nodular hyperplasia (FNH) is not a genuine tumor.In path ology,FNH is a hyperplastic response of normal hepatic cell to congenital or acq uired abnormal blood vessels.The mass consists of abnomal blood vessels,normal h epatic cells,Kuffer cells,bile ducts and hyperplastic fibrous connective tissue .Typical CT features includes evident uniform enhancement of the hypervas cular mass on hepatic arterial phase,an earlier portal vein phase,and delayed e nhancement of central scar.FNH always shows iso-or slightly long T 1 and iso o r slightly long T 2 signal intensity on MR imaging,while the central scar has a hypoint ensity on T 1WI and hyperintensity on T 2WI.Contrast enhancement with SPI O is helpful to diagnose this disease. |
