巨脑白质病变伴皮下囊肿

Megalencephalic leukoencephalopathy with subcortical cysts

ORPHA:2478疾病

定义 英文原文(暂无中文)

A form of leukodystrophy that is characterized by infantile-onset macrocephaly, often with mild neurologic signs at presentation (such as mild motor delay), which worsen with time, leading to poor ambulation, falls, ataxia, spasticity, increasing seizures and cognitive decline. Brain magnetic resonance imaging reveals diffusely abnormal and mildly swollen white matter as well as subcortical cysts in the anterior temporal and frontoparietal regions.
