摘要 目的 :通过归类分析肝脏局灶性含脂病变的脂肪存在形式特征,结合病史、临床特征、磁共振成像(magnetic resonance imaging,MRI)表现及周围征象,从而提高对肝脏局灶性含脂病变的诊断与鉴别诊断的准确率。方法:经手术病理证实或典型表现及长期随访确定的肝脏含脂病变45例,均采用GE Signa Twinspeed 1.5T或3.0T全身磁共振检查仪进行多期相扫描,并分析病变的病史、临床特征、脂肪存在形式、MRI多期表现及周围征象,分析病变的特征性;并较脂肪成分归类+MRI特征分析结合方法与以往方法对诊断肝脏含脂病变的准确率。结果:肝脏局灶性含脂病变45例中,原发性肝细胞肝癌12例,肝血管平滑肌脂肪瘤(angiomyolipoma of liver,AML)10例,脂肪瘤4例,肝癌术后病例9例,肝腺瘤5例,包膜假结节样脂肪浸润5例;脂肪形式:表现为细胞内脂肪成分的主要为含脂肝癌、肝腺瘤,表现为相对较大脂肪组织的主要有脂肪瘤、肝癌术后网膜脂肪填充及包膜下假结节样脂肪浸润;肝AML的脂肪存在形式无特异性。结论:通过对肝脏局灶性含脂病变的脂肪表现形式分析,结合病史、临床特征及MRI特征性表现,可进一步提高影像诊断的准确率,缩小鉴别诊断的范围。
