Project description:Hemichorea-hemiballism can be the solely presentation of a wide range of non-neurological clinical pictures, such as metabolic or hydro-electrolyte derange-ments. Hemichorea-hemiballism as the first presentation of type 2 diabetes mellitus has been described. The case depicted herein reinforces this association highlighting that especially in elder patients with new-ly diagnosed hemichorea-hemiballism, non-ketotic hyperglycemia should promptly be recognized.

Hemichorea-Hemiballism in A 50-Year-Old Man With Newly Diagnosed Diabetes.

Project description:ObjectiveHyperglycemia may cause acute central nervous system dysfunction manifesting as agonizing involuntary movements due to insult to the basal ganglia. We report a case of hemichorea-hemiballism (HCHB) in a patient with diabetes.MethodClinical assessment of the patient was performed, along with laboratory tests and brain imaging.ResultsThe patient was a 50-year-old man with newly detected diabetes with persistent involuntary movement of the right upper and lower limbs for few weeks. The involuntary movement was nonrhythmic, nonpatterned, purposeless, and often jerky with variable amplitude and frequency, sometimes wild and flailing in the form of hemichorea with a ballistic component (HCHB). He had a history of poor compliance to prescribed oral antidiabetic drugs. At presentation, although he was hemodynamically stable, random capillary blood glucose level was 18 mmol/L and glycated hemoglobin A1 level was 15.1% (141.5 mmol/mol). Clinical examination did not reveal any focal deficit or positive Babinski sign. There was a hyperintensity in the left basal ganglia region in T1-weighted magnetic resonance imaging (MRI) of the brain, which was iso-to-hyperintense in T2-weighted image and fluid-attenuated inversion recovery sequence. There was no restriction of diffusion on the diffusion-weighted image or blooming on gradient echo sequences, indicating absence of infarction or hemorrhage. Control of hyperglycemia resulted in disappearance of the involuntary movement within 1 month.ConclusionWhile there are many differential diagnoses for HCHB, the clinical scenario suggests hyperglycemia as the underlying cause in this patient. This case reiterates that multiple central nervous system manifestations may be attributable to diabetes.

Ipsilateral Hemichorea-hemiballism in a Case of Postoperative Stroke.

Project description:Ipsilateral hemiballismus refers to the rare occurrence of hemiballism developing on the same side of a brain lesion.We describe a rare case of postoperative ipsilateral hemiballism in a patient who underwent pituitary adenoma resection and experienced a right internal cerebral artery territory infarct. We review the literature on hemichorea hemiballismus (HCHB) and explore various mechanisms for its occurrence.Only three cases of ipsilateral hemiballism have been described, and the exact pathophysiology remains unknown. A dominant left hemisphere with corpus callosal connections to the right basal ganglia is the most probable explanation for this unusual event.

Isolated truncal contrapulsion as a rare presentation of acute thalamic infarct.

Project description:Infarcts involving the thalamus can yield many deficits, including sensory syndromes, altered consciousness, and cognitive disturbances, depending on the thalamic vascular territory involved. Isolated truncal contrapulsion due to pure thalamic infarct has been rarely reported. Truncal lateropulsion is a compelling sensation of being pulled toward one side that cannot be explained by weakness or limb ataxia. It is commonly reported in lateral medullary infarcts. It may occur with lesions that involve the peripheral vestibular system, brainstem, cerebellum, basal ganglia, ponto-mesencephalic, and thalamic lesions. We hereby report a 64-year-old woman who presented with truncal contrapulsion as the sole manifestation of an acute right lateral thalamic infarct.
