Object: Cortical malformations and inflammatory encephalopathy are among common etiologies for medically refractory epilepsy in children. On rare occasions, lesions can affect an entire cerebral hemisphere while sparing the other; the 2 processes that can manifest in this manner are hemimegalencephaly (HME) and Rasmussen's encephalitis (RE). Although the clinical course and radiological appearance between the 2 disorders are distinct, there is occasional overlapping pathology between RE and cortical migration disorders.

We present a case of an incidentally discovered holohemispheric developmental venous anomaly (DVA) in a 12 year old, conclusively characterized by 3D T2* multi-echo sequence susceptibility weighted angiographic imaging (SWAN). For the evaluation of head trauma, abnormal right intraparenchymal and periventricular vascularity was identified by a non contrast head CT scan. Conventional MRI sequences revealed prominent veins with findings suspicious of a DVA.

Crossed cerebellar atrophy in children: a neurologic sequela of extreme prematurity.

Unilateral atrophy of a cerebellar hemisphere occurring as a sequela of ischemic or destructive injury of the contralateral cerebral hemisphere is uncommon in children. We reviewed our experience with this phenomenon and found an unexpected association with extreme prematurity and a complicated perinatal course with a poor subsequent neurologic outcome. We retrospectively identified eight children, aged 8 months to 13 years, in whom cerebellar atrophy associated with cerebral injury was diagnosed on MR or CT, and reviewed their past medical history, neurologic findings, and neuroimaging studies.
