Hypoglycemic encephalopathy manifesting with hemiballismus and contralateral cortical fronto-parietal lesions

Abstract

Severe hypoglycemia is associated with a broad range of neurological deficits and alterations on cerebral magnetic resonance imaging (MRI). Typically, hypoglycemic encephalopathy causes symmetrical lesions to the cerebral cortex, with temporal lobes and basal ganglia appearing most susceptible. Cortical involvement usually correlates with a poor functional outcome.
