Alexander disease is a rare autosomal recessive disorder that is characterized by degeneration of the white matter in the central nervous system. Alexander disease is a leukodystrophy that is usually observed in early childhood but rarely in adults. It is characterized by megalencephaly, demyelinization and multiple Rosenthal fibers. Specific magnetic resonance imaging (MRI) findings and genetic investigations are necessary to diagnose the disorder. Signs of leukodystrophy were found in the bilateral white matter on a brain MRI of our four-year-old patient. He had megalencephaly since birth. We use this case to discuss Alexander disease.
