Chorea in the Both Lower Limbs Associated with Nonketotic Hyperglycemia
نویسندگان
چکیده
Hemichorea-hemiballism (HC-HB) is a complication of non-ketotic hyperglycemia (NKH); in NKH patients, the frequency of occurrence of HC-HB is greater than that of bilateral chorea. We report the case of a hyperglycemic patient who showed chorea in both the lower limbs. Magnetic resonance imaging (MRI) of the brain revealed high signal intensity on T1-weighted images of the bilateral dorsolateral putamen. The abnormal involuntary movements disappeared after oral administration of haloperidol. Our case report that chorea associated with NKH is correlated with the topography of the basal ganglia.

Classic neuroimaging findings of nonketotic hyperglycemia on computed tomography and magnetic resonance imaging with absence of typical movement disorder symptoms (hemichorea-hemiballism).
While there are broad differential diagnoses for either the clinical finding of hemichorea-hemiballism or the imaging finding of lateralizing/asymmetric basal ganglia lesions (hyperdense on computed tomography, hyperintense on T1 magnetic resonance imaging), the presence of both findings is highly suggestive of nonketotic hyperglycemia. We present an unusual case of a patient with vague stroke-...

A 75-year-old Asian man presented with two episodes of chorea associated with nonketotic hyperglycemia. His chorea rapidly resolved after restitution of a normal serum glucose level, although an MR image obtained at the time of acute symptoms demonstrated high signal intensity on T1-weighted images, low signal intensity on T2-weighted images, and restricted diffusion, all involving the left put...

The chorea was continuous and could not be suppressed voluntarily, although it disappeared during sleep. It gradually worsened over the following days, involving the left face, left arm, left leg, and the right leg to a lesser degree. The patient also showed frequent, re...
