| 目的 分析肝脏富血供良性占位的CT及MR特征性表现及鉴别诊断。方法 回顾性分析经病理证实的37例肝脏富血供良性占位患者的资料，包括肝脏局灶性结节增生（FNH）24例（FNH组）、肝腺瘤（HCA）6例（HCA组）、肝脏血管平滑肌脂肪瘤（HAML）7例（HAML组）；对比观察各组CT及MR征象。结果 3组间中央瘢痕（有、无）、病灶内脂肪（有、无）、供血动脉（有、无）、引流静脉（有、无）及动脉期强化程度（是否明显强化）差异均有统计学意义（P均<0.01），假包膜（有、无）征象差异无统计学意义（χ2=0.67，P=0.67）。结论 中央瘢痕、病灶内脂肪、动脉期明显强化、供血动脉及引流静脉可作为FNH、HCA及HAML的鉴别诊断指标。 |

| Objective To analyze the characteristic CT and MR manifestations of benign space-occupying lesions with hypervascular in liver and the differential diagnosis. Methods A retrospective analysis of 37 cases of benign space-occupying lesions with hypervascular in liver confirmed by pathology was performed. There were 24 cases of focal nodular hyperplasia (FNH, FNH group), 6 cases of hepatic adenoma (HCA, HCA group) and 7 cases of hepatic angiomyolipoma (HAML, HAML group). CT and/or MR manifestations were observed and compared. Results There were statistic differences of the central scar (with or without), intralesional fat (with or without), feeding artery (with or without), drainage vein (with or without) and the degree of enhancement of the arterial phase (whether it was significantly enhanced) among the three groups (all P<0.01). The sign of pseudo-envelope (with or without) was not statistically different (χ2=0.67, P=0.67). Conclusion The central scar, intralesional fat, arterial phase significantly enhanced, feeding artery and drainage vein can be used as differential diagnostic indicators for FNH, HCA and HAML. |
