title: Striatal hemihypoplasia: an early embryonic variant of cerebral hemiatrophy.
abstract: We present a case of hemihypoplasia of the striatum with ipsilateral cerebral hemispheric atrophy. The head of the caudate nucleus and putamen were hypoplastic, and gray matter cell bridges between them located in the anterior limb of the internal capsule were sparse. Cerebral atrophy was accompanied by ipsilateral mesial temporal sclerosis without thalamic atrophy. The anterior limb of the internal capsule showed no signal abnormalities or volume loss. These imaging findings and the hyperintensity at the fundus striati suggest an early embryonic insult of lateral striatal elevation.
