Abstract We reviewed the MRI of 17 patients with hemimegalencephaly to investigate abnormal myelination in this condition. On images of seven patients aged 18 months or less, the white matter on the affected side suggested advanced myelination for the age. On T1-weighted images of three patients aged 1 month, the anterior limb of the internal capsule in the affected hemisphere was myelinated, and T1 shortening was not clearly seen in the pre- and postcentral gyri. The cortical grey matter and subcortical white matter was isointense in two patients. Images of two patients aged 4 to 5 months and of five patients aged 8–18 months showed myelination that extended more peripherally in the white matter of the affected hemisphere.
