引用ssm999在2006-10-31 20:20:00的发言:急性播散性脑脊髓炎(acute disseminated ence-phalomyelitis, adem)也称免疫介导性脑脊髓炎,是一种少见的中枢神经系统脱髓鞘疾病,多数在发病前数天至数周有病毒感染或疫苗接种史,少部分无明确诱因。本病是自体免疫损伤所致的脱髓鞘疾患而不是病毒性脑炎。
支持adem的诊断。病史比较重要,其实左侧放射冠区白质亦见低密度,下面是我收到的一幅图片和英文资料。
adem is a neurologic disorder characterized by inflammation and damage to the myelin sheath of the brain and spinal cord, likely from a transient autoimmune response. it is a monophasic syndrome that is usually preceded by a viral illness, an upper respiratory infection, or vaccination. viruses that have most commonly been associated with adem are measles, paramyxovirus, varicella, rubella, and epstein-barr virus, although, with the advent of successful vaccination campaigns, the incidence of adem with these viruses (eg, measles) is dramatically reduced. as such, because of adem';s association viruses typically occurring in childhood, the disease occurs in children younger than 10 years approximately 80% of the time; only 3% of cases occur in adults.![]()
