摘　　要：目的分析核磁共振(MRI)在不同临床分期瘤样脱髓鞘病变(TDLs)患者中的影像特点。方法选取经病理证实的90例TDLs患者作为分析对象。根据患者病变情况将其分为急性期、亚急性期、慢性期,对不同临床分期TDLs患者行头颅MRI检查,归纳其影像特点并比较差异。结果急性期、亚急性期、慢性期患者各强化特点差异均具有统计学意义(P<0.05);与亚急性期和慢性期比较,急性期患者斑片状及结节样强化明显较多,差异有统计学意义(P<0.05);与急性期和慢性期比,亚急性期患者以病灶边缘强化多见,差异有统计学意义(P<0.05);与急性期和亚急性期相比,慢性期患者主要表现为浅淡斑片状差异有统计学意义(P<0.05)。结论TDLs患者头颅增强MRI结果随其临床分期呈动态演变特性,对TDLs的临床诊断与鉴别诊断具有一定的参考价值。Objective To analyze the imaging characteristics of MRI in patients with different clinical stages of tumefactive demyelinating lesions(TDLs).Methods 90 patients with TDLs confirmed by pathology were selected as the analysis subjects.The patients were divided into acute stage,subacute stage and chronic stage according to the disease condition.Cranial MRI examination was performed on patients with TDLs in different clinical stages,and the imaging characteristics were summarized and compared.Results There were statistically significant differences in the enhancement characteristics among patients in acute stage,subacute stage and chronic stage(P<0.05).Compared with subacute stage and chronic stage,the patchy and nodular enhancements were significantly higher among patients in acute stage(P<0.05).Compared with acute stage and chronic stage,the lesion marginal enhancement was more common in patients in subacute stage(P<0.05).Compared with acute stage and subacute stage,the light patchy enhancement was mainly showed in patients in chronic stage(P<0.05).Conclusion Cranial contrast-enhanced MRI results of patients with TDLs show dynamic evolution characteristics with the clinical stages,which has a certain reference value for the clinical diagnosis and differential diagnosis of TDLs.
