Diabetic striatopathy

Nonketogenic hyperglycemic hemichorea, also recognized as diabetic striatopathy, is a rare manifestation of diabetes mellitus. The diagnosis of nonketotic hyperglycemic hemichorea is usually made through imaging along with a corresponding clinical picture. Early identification and treatment can lead to complete resolution of the symptoms and better patient outcomes. Here we present a 49-year-old female patient, with a past medical history of poorly controlled type 2 diabetes mellitus and prior left index finger amputation as a complication of her diabetes, who presented for evaluation of a two-week duration of sudden-onset left upper extremity choreiform movements...

BACKGROUND AND AIMS: Acute onset de novo movement disorder is an increasingly recognized, yet undereported complication of diabetes. Hyperglycemia can give rise to a range of different movement disorders, hemichorea-hemiballism being the commonest. This article delves into the current knowledge about this condition, its diverse presentations, ongoing debates regarding its underlying mechanisms, disparities between clinical and radiological findings, and challenges related to its management...

BACKGROUND: Diabetic striatopathy, also known as hyperglycemic hemichorea-hemiballismus, is a rare movement disorder associated with nonketotic hyperglycemia in patients with poorly controlled diabetes mellitus. The pathophysiology is not fully elucidated but may involve hyperviscosity, ischemia, and alterations in basal ganglia neurotransmitters. CASE PRESENTATION: We present a case of a 64-year-old Asian female patient with longstanding poorly controlled type 2 diabetes mellitus who developed abrupt-onset right-sided hemichorea-hemiballismus...

Diabetic striatopathy, a rare condition also known as hyperglycemic nonketotic hemichorea, is characterized by chorea or hemiballismus and distinctive basal ganglia abnormalities visible on neuroimaging. We present the case of an 86-year-old woman with diabetic striatopathy exhibiting hemichorea. She had a history of poorly controlled type 2 diabetes and presented with involuntary movements of her left limb along with facial expressions suggestive of chorea. Laboratory tests confirmed hyperglycemia, with an elevated hemoglobin A1c level...

Diabetic striatopathy is a rare condition with a prevalence of less than one in 100,000. Herein, we report a case of diabetic striatopathy exacerbated by hyperglycemia and hypoglycemia, with repeated follow-up with multiple imaging studies. This case suggested that putamen neuronal loss and dysfunction, gliosis, and ischemia are associated with diabetic striatopathy pathophysiology. In addition, striatal hyperintensity on T1-weighted MRI images was more pronounced after symptom remission when evaluated several times over a short period...

Diabetic striatopathy is a rare neurological complication of diabetes mellitus that presents with sudden onset hemichorea or hemiballismus and is associated with hyperglycemia and striatal abnormality, either by hyperdensity on non-contrast computer tomography or hyperintensity on T1-weighted magnetic resonance imaging. Here we report a 55-year-old female, from Sri Lanka, who presented with involuntary movements of the left upper and lower limbs. Her past medical history included diabetes mellitus and she was on warfarin 5 mg daily for a mechanical mitral and tricuspid valve replacement...

Diabetic striatopathy is a clinicoradiological syndrome characterised by acute hyperkinetic movement disorder in the form of hemichorea-hemiballism with basal ganglia abnormalities in neuroimaging. The hallmark basal ganglia abnormalities appear as hyperdensities in CT brain and hyperintensities in MRI brain, which could mislead the clinician towards an erroneous diagnosis of cerebral haemorrhage. It is classically described in elderly patients with type 2 diabetes mellitus, and its occurrence in type 1 diabetes is extremely rare...

Diabetic striatopathy (DS) is a rare central nervous system complication of diabetes mellitus, characterized mainly by non-ketotic hyperglycemia and lateralized involuntary movements. Patients with diabetic striatopathy manifested solely by subacute cognitive decline were rarely reported. In this paper, we report a patient with DS who presented solely with subacute cognitive decline without involuntary movements, and cranial CT showed bilateral high density in the basal ganglia. In contrast, SWI showed microhemorrhages in the right caudate nucleus head...

Case report : An 83-year-old Italian female developed postural instability and gait disturbance associated with a concomitant hyperosmolar hyperglycemic state. Brain CT and MRI scans detected a lesion in the right putamen due to metabolic derangement. A month later, the patient started suffering from choreic movements along the left side of the body with brachio-crural distribution, approximately three weeks after SARS-CoV-2 infection. She was treated with tetrabenazine with complete resolution of the aberrant movements...

BACKGROUND: Diabetic Striatopathy (DS) is a rare complication of a poor-controlled Diabetes Mellitus consisting of sudden onset of movement disorders. To date, there is still poor knowledge about the pathogenesis. CASE: We describe a 79 year old men affected by sudden onset hemichoreic movements whose cause was a non-ketotic hyperglycaemia diagnosed despite the normal blood glucose levels thanks to brain CT and magnetic resonance imaging. Then, we introduce a new magnetic resonance spectroscopy (MRS) finding never described until today which allowed us to produce a new pathogenetic theory of a phenomenon still without definitive explanations...

Diabetic striatopathy (DS) is a condition occurring in individuals with type II diabetes mellitus (T2DM) where there are abnormal (usually single-sided) bodily movements (hemiballismus-hemichorea (HBHC)). DS involves the interaction between diabetes leading to damage to areas such as the striatum with the development of a noticeable hyperkinetic movement disorder. Here, we present a case of a 72-year-old man with T2DM, ischaemic heart disease, and dyslipidaemia, who presented with involuntary movements of the bilateral upper limbs (the left side more affected than the right) for three weeks along with progressively worsening subtle involuntary movements of the mouth and tongue, with intact speech, swallowing, and gait...

PURPOSE: To present a rare case of diabetic striatopathy in a child with type 1 diabetes mellitus with reversible unilateral hemichorea hemiballismus. CONCLUSION: A high index of suspicion is required to make a diagnosis of DS in children presenting with abnormal movement disorder and characteristic neuroimaging findings in a background of uncontrolled DM.

We present the case of an 83-year-old female patient with left-side hemichorea and hemiballism associated with poorly controlled type 2 diabetes mellitus. Hyperintensity in the right basal ganglia was evident in T1-weighted brain magnetic resonance. Clinical and radiological findings were consistent with diabetic striatopathy.

PURPOSE: Diabetic striatopathy (DS) is a rare complication of poorly controlled diabetes mellitus (DM), characterized by hyperglycemia associated with chorea/ballism and characteristic reversible basal ganglia abnormalities on computed tomography (CT) and/or magnetic resonance imaging (MRI). We propose a narrative review of the literature on this topic, currently unknown to most, and about which physicians should be aware. We intend to summarize, critically review, and take to mean the evidence on this disorder, describing its typical features...

BACKGROUND: Nonketotic hyperglycemic hemichorea is a rare complication of diabetes mellitus seen in the emergency department. It is most commonly reported in elderly women, predominantly of Asian race, with poorly controlled diabetes mellitus. Patients present with a triad of nonketotic hyperglycemia, hemichorea, and contralateral basal ganglia abnormality on imaging. Its exact pathophysiology is still not known. However, it has a very good prognosis with early diagnosis and treatment...

Diabetic striatopathy (DS) is a rare condition present as a combination of hemichorea or hemiballismus with striatal computed tomography (CT) or magnetic resonance imaging (MRI) changes in the presence of a severely hyperglycemic state. Varying severity and manifestations of DS were reported throughout the literature. However, the exact pathogenesis and mechanism remain unclear. In this case report, we are presenting an unusual case of DS combined with acute ischemic stroke. A 74-year-old male presented with the main complaint of acute left arm and leg weakness, and was found to have significantly high blood sugar and evidence of DS in combination with stroke on CT and MRI...
