Infections of central nervous system (CNS) include a broad group of conditions and pose a particular challenge to physicians, especially in immunocompromised individuals. This case refers to a 26-year-old male patient with a history of smoked hashish and drug abuse admitted to the infectious disease department with hemiballismus of left hemibody and a positive HIV serologic test. A magnetic resonance imaging (MRI) study showed lesions at lower left and right cerebellar hemisphere, one of them thalamus - mesencephalic suggesting an opportunistic infection or an HIV associated encephalopathy...

OBJECTIVE: To determine whether neuroanatomically heterogeneous strokes causing hemichorea-hemiballismus localize to a common functional network. METHODS: We identified 29 cases of lesion-induced hemichorea-hemiballismus from the literature and mapped each lesion volume onto a reference brain. Using a recently validated technique termed lesion network mapping, we tested whether these lesions belonged to the same functional network. To accomplish this, the network of brain regions functionally connected to each lesion was identified using a connectome dataset from healthy participants...

BACKGROUND: Ipsilateral hemiballismus refers to the rare occurrence of hemiballism developing on the same side of a brain lesion. CASE REPORT: 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. DISCUSSION: Only three cases of ipsilateral hemiballism have been described, and the exact pathophysiology remains unknown...

A 68-year-old woman with poorly controlled diabetes mellitus presented to the emergency department with choreoathetoid movements affecting the upper and lower left limbs. Computed tomography of the brain did not show any intracranial abnormalities. However, subsequent magnetic resonance (MR) imaging of the brain revealed an increased T1 signal in the right basal ganglia, raising the suspicion of nonketotic hyperglycaemic chorea-hemiballismus. Management consisted of adjusting her insulin dose to achieve good glycaemic control...

We report an unusual case of delayed bilateral, right greater than left hemiballismus in a 15-year-old female patient with a history of a craniopharyngioma 2years following the insertion of a right intratumoral chemotherapy catheter. Following cyst decompression, the catheter was found to have changed position, traversing the basal ganglia structures, namely the right subthalamic nucleus. Her movement disorder near-completely resolved immediately following removal of the catheter. A review of the current literature and proposed pathophysiological mechanisms are discussed...

CONTEXT: Hemiballismus is characterized by involuntary, irregular, large amplitude, and violent flinging movements of limbs. Stroke (middle and posterior cerebral artery) remains the most common etiology with 2/3 being lacunar. Lesions outside the substantia niagra (STN) can cause hemiballism, and only a minority by STN lesions, unlike the classical belief. Compared to those arising from STN, cortical hemiballismus is usually less severe with a good prognosis. CASE REPORT: A 61-year-old man presented with sudden onset involuntary flinging movements of his right upper extremity accompanied by numbness and tingling...

Hyperglycaemia induced movement disorders, such as hemiballism are rare disorders. The syndrome is characterised by the triad of hemiballism, contralateral T1-hyperintense striatal lesion and non-ketotic hyperglycaemia. Here we report a patient with untreated diabetes presenting with acute onset of hemiballism. MRI revealed T1 hyperintensity of the head of the caudate nucleus and the anterior putamen. The patient also had acantocytosis. Based on the detailed examination of the neuroradiological results and earlier findings we will discuss the pathomechanism...

Hemiballismus is a rare presentation of symptomatic carotid stenosis that is underreported in the neurosurgical literature. It is characterized by severe, large amplitude movements that are classically caused by lesions of the subthalamic nucleus. Given the arterial border zone position of the subthalamic nucleus between the anterior and posterior circulation, hemodynamically compromising carotid stenosis can lead to hypoperfusion in this location. We describe the case of a patient who presented with acute-onset hemiballismus that had complete resolution of symptoms after carotid endarterectomy...

We present an 89-year-old man with new onset of left-sided hemiballismus affecting his face, arm and leg. He was found to have hyperglycaemia with a glucose level of 20.2 mmol/l and had started prednisolone 3 months earlier for polymyalgia rheumatica. A T 2-weighted magnetic resonance scan of the brain showed a hypointense lesion of the right lentiform nucleus. At follow-up, his symptoms had improved with treatment for diabetes mellitus. To our knowledge, this is the first patient to develop hemiballismus after starting corticosteroids...

BACKGROUND: demonstrate the importance of considering limb-shaking syndrome in the differential diagnosis of patients who present to the emergency department (ED) with hyperkinetic movements. METHODS: In this article, we describe a diagnostic challenge in the ED in which a patient presents with hyperkinetic movements that are initially diagnosed as hemichorea-hemiballismus (HCHB) but are subsequently found to be limb-shaking syndrome with important therapeutic opportunities...

Non-ketotic hyperglycemia is an unusual and rare cause of hemichorea-hemiballismus. Correction of the hyperglycemia usually results in total resolution of the signs and symptoms. We present the case and medical imaging findings of a 66-year-old female who presented with steadily worsening choreiform and ballistic movements of the right upper and lower extremities over a 2-week period. Her serum glucose was greater than 600 mg/dL, and no ketones were present. CT scan and MR demonstrated left basal ganglia abnormalities suggesting hyperglycemia-related hemichorea-hemiballismus syndrome...

BACKGROUND: Movement disorders after the clipping for an unruptured giant aneurysm are rare. The information on the pathogenesis and treatment options for this condition is largely unknown. CASE DESCRIPTION: An 82-year-old female with no neurological deficits underwent a clipping for a giant middle cerebral artery (MCA) aneurysm. Immediately after surgery, she presented with hemichorea-hemiballismus (HC-HB) on the left side. Postoperative angiograms and single-photon emission computed tomography demonstrated the hyperperfusion in the right frontal cortex and the decreased perfusion in the basal ganglia, indicating that the abrupt hemodynamic changes due to the obliteration of the giant aneurysm caused the dysfunction of the frontal cortical and subcortical pathway and the basal ganglia...

Hemichorea hemiballismus (HCHB) is a rare and debilitating presentation of hyperglycemia and subcortical stroke. Early identification, proper assessment and management of HCHB can lead to complete symptom relief. We describe a case of HCHB presenting to a palliative care setting. A 63-year-old diabetic and hypertensive lady, with history of ovarian cancer presented to Palliative Medicine outpatient clinic with two days history of right HCHB. Blood investigations and brain imaging showed high blood sugar levels and lacunar subcortical stroke...

The nature of electromyogram (EMG) activity and its relationship to neuronal activity in the internal globus pallidus (GPi) have not previously been studied in hyperkinetic movement disorders. We now test the hypothesis that GPi spike trains are cross-correlated with EMG activity during apomorphine-induced dyskinesias of Parkinson's disease (AID), and Hemiballism. We have recorded these two signals during awake stereotactic pallidal surgeries and analyzed them by cross-correlation of the raw signals and of peaks of activity occurring in those signals...

Chorea may be secondary to hyperosmolar nonketotic hyperglycemia, but such situation has rarely been described in adolescents, particularly as the initial and single manifestation of type 1 diabetes. We describe a case of a previously healthy 14-year-old girl with sudden onset of choreic movements on her left upper and lower limbs. Brain computed tomography (CT) and magnetic resonance imaging (MRI) revealed an area of hyperdensity/hyperintensity affecting the right striatum. Blood glucose was 349 mg/dL. Despite adequate glucose control, the involuntary movements persisted and haloperidol, later substituted with valproate, was prescribed, with satisfactory but not complete resolution of the chorea...
