Infantile Alexander disease: A rare leukodystrophy.

Infantile Alexander disease (AD) is a rare leukodystrophy characterized by its early onset within 2 years of life and clinically presents with macrocephaly, seizures, and retarded psychomotor development. Magnetic resonance imaging (MRI) shows characteristic symmetric white matter abnormalities with frontal predominance. We present a case of infantile AD with typical clinical characteristics and MRI features.
