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